Windows 11 Canary Build 27924: Copilot+ AI, Advanced Settings, and Risks

  • Thread Author
Today’s Canary-channel flight, Windows 11 Insider Preview Build 27924, marks a significant push by Microsoft into earlier-stage platform experimentation — and it ships with a packed, sometimes contentious mix of AI-driven features for Copilot+ PCs, new system-level settings, app updates, and several sharp reminders about the risks of running bleeding-edge builds.

Overview​

Microsoft has released Windows 11 Insider Preview Build 27924 to the Canary Channel and published downloadable ISOs for testers. The build begins to enable a wider set of Copilot+ PC experiences — notably features such as Recall (Preview), Click to Do (Preview), improved Windows Search, live captions with real-time translation, and an Agent in Settings — alongside a new Advanced Settings hub in Settings, changes to input and system services, and an update to the Snipping Tool that introduces window mode screen recording. Microsoft warns that Canary-channel quality will lag Dev and Beta, that feature rollouts are gradual, and that some experiences may never ship to the general public.
This article breaks down what’s new, what matters to IT professionals and enthusiasts, the practical implications of the Copilot+ feature set, and a clear assessment of the trade-offs — including stability, privacy, and deployment risks — so readers can make an informed decision about testing Build 27924.

Background: Canary Channel and the new Insider landscape​

The Canary Channel is deliberately positioned as the earliest public channel for platform-level work. It receives high build numbers and changes that are closer to raw engineering output, including kernel-level and API work that require a longer lead time. Because these builds are “hot off the presses,” they typically ship with minimal documentation and limited internal validation.
  • The Canary Channel is intended for early experimentation with platform-level ideas that may never ship.
  • Insiders in Dev historically received similar builds but some Dev insiders were migrated to Canary; switching to another Insider channel later often requires a clean installation.
  • Expect limited documentation, bigger regressions, and higher instability than Dev or Beta.
For readers who follow Insider flights closely, that context explains why Build 27924 includes high-impact features and system redesigns while also shipping with significant caveats and known issues.

What’s new in Build 27924​

Copilot+ PC experiences (Preview rollout)​

Build 27924 begins enabling several Copilot+ PC experiences to Canary Insiders on supported hardware. The Copilot+ program targets PCs with on-device AI accelerators (NPU), and the features in this flight are explicitly labeled preview or gradual-rollout.
Key Copilot+ experiences included in this flight:
  • Recall (Preview): A local snapshot-and-search experience that lets users find previously viewed apps, files, websites, and visual content by searching across a timeline of snapshots.
  • Click to Do (Preview): An AI overlay that analyzes screen content (text and images) and offers contextual actions — for example, summarization, copy, visual search, or integration with Copilot for a follow-up action.
  • Improved Windows Search: Search enhancements that benefit from Copilot capabilities and possibly tighter integration with on-device models.
  • Live captions with real-time translation: Expanded live caption functionality that can translate spoken content in real time.
  • Agent in Settings: An AI-driven agent surfaced inside Settings to assist with configuration tasks.
Important operational notes about these features:
  • Many items are rolled out gradually via feature gating mechanisms. Not every Copilot+ PC running this build will immediately see every feature.
  • On-device models and runtime components (for example, Phi Silica) are central to Click to Do’s intelligent text actions and are designed to run locally, leveraging NPU resources where available.
  • Copilot+ functionality is tightly tied to hardware support and platform prerequisites; some features will only appear on certified Copilot+ devices.
Analysis: The Copilot+ push shows Microsoft’s intent to embed more persistent, local AI capabilities into Windows’ core UX. Running these services locally (rather than routing all content to the cloud) can reduce latency and help with privacy claims — provided the implementation avoids edge-case leaks or misconfigurations. However, these features expand attack surface and raise new privacy, data retention, and compliance questions for users and organizations.

Advanced Settings — a redesign and new controls​

Build 27924 introduces Advanced settings under Settings > System > Advanced, a redesigned hub aimed at making developer and system-level toggles accessible to a broader audience.
Highlighted additions:
  • Enable long paths: A switch to remove legacy MAX_PATH limitations in Win32 APIs.
  • Virtual workspaces: Quick toggles for virtualization platforms and environments (Hyper-V, Windows Sandbox, and similar).
  • File Explorer + version control: Git metadata and version-control niceties surfaced in File Explorer (branch, last commit message, diff counts) for folders that are repositories.
This redesign repackages some developer-oriented options for power users while adding integration points for developer workflows directly into the shell.
Analysis: File Explorer integrating Git metadata is smart ergonomics for developers; it reduces context switching. The long-path toggle simplifies a trip into Group Policy or registry edits. The key question is how these controls are exposed for corporate admins — policy controls and MDM settings will be necessary for enterprise rollouts.

Snipping Tool: window mode screen recording​

The Snipping Tool in this flight receives an update (noted to be version 11.2507.14.0 and higher in this rollout window) that introduces window mode for screen recordings. When selected, the Snipping Tool will size recordings to match the selected app window and keep that fixed recording region for the session.
Why this matters:
  • It makes ad-hoc app-window recordings simpler and faster without manual cropping after capture.
  • The region is fixed once recording starts; if the app moves or is occluded, the recording will not follow. That is a deliberate design trade-off for determinism.
The Snipping Tool updates in recent Insider flights also include improved capture bar integration and audio options, reflecting a steady investment in built-in capture functionality.

Changes, improvements, and developer-facing updates​

Build 27924 lists multiple platform and service changes:
  • Pointer indicator transparency and shortcut change: The pointer indicator transparency was adjusted for clarity, and the keyboard shortcut changed from Ctrl + Win + X to Ctrl + Win + Alt + X to avoid accidental triggers.
  • Windows MIDI Services breaking change: The inbox preview MIDI Service and API introduced a breaking change related to how m-sending waits are handled. Apps written against prior preview SDKs must be recompiled against the latest preview and may need code changes to continue working.
  • MIDI community feedback channels: Microsoft has referenced a community Discord for feedback and discussion on MIDI services — an unusual, developer-centric community approach for low-level features.
  • Other stability fixes: Fixes to explorer crashes, widgets disappearing, remote desktop monitor handling, and an underlying webauth.dll crash that could affect passkey use.
Developer impact: The MIDI change is a concrete breaking API shift; developers shipping audio or MIDI-aware software should test with the latest preview SDKs and recompile to avoid runtime failures. The build emphasizes that certain platform changes in Canary are intended for early developer discovery and adaptation.

Fixes and known issues: what to expect​

Build 27924 contains fixes and a candid list of known issues that highlight trade-offs of Canary testing.
Notable fixes:
  • Resolved rendering/upgrade glyph bug (progress wheel rendered as rectangle).
  • Fixed widgets reliability issues where widgets disappeared.
  • Repaired a remote desktop regression forcing single-monitor rendering.
  • Fixed a webauth.dll crash impacting passkey use.
Known issues that matter:
  • On Copilot+ PCs, users who switch to the Canary Channel from Dev, Release Preview, or retail may temporarily lose Windows Hello PIN and biometrics and encounter error 0xd0000225. Microsoft says the PIN can be recreated; however, this is a significant friction point for any tester who relies on Windows Hello.
  • The build includes an underlying dao360.dll issue that may cause some apps to crash.
  • Click to Do has a known issue where text and image actions may not work and Click to Do can crash; Microsoft expects a fix in the next flight.
  • Canary builds may not document all issues; only the most impactful ones are enumerated.
Analysis: The Windows Hello regression is the most consequential practical issue; losing PIN/biometrics creates real workplace friction and — in some cases — lockout scenarios that complicate testing. The presence of a DLL-level app crash risk and documented instability for Click to Do reinforces that Canary is not for primary devices or production environments.

Privacy, security, and regulatory implications​

The Copilot+ experiences — especially Recall — raise important privacy and security questions. Recall’s model of frequent snapshots and local indexing for "retracing your steps" is powerful for productivity but requires careful engineering around sensitive data handling.
Key privacy considerations:
  • Snapshot capture scope: Snapshotting may capture screen content that includes passwords, personal identifiers, or sensitive documents. Microsoft documents filtering mechanisms and user controls for excluding apps, websites, and in-private browsing, and claims data remains local and encrypted.
  • Local encryption and key management: The preview model ties Recall to Windows Hello and local keys; if Windows Hello is removed, keys may be inaccessible. Microsoft has signaled future support for backup/export of keys and data.
  • Filtering reliability: Early reports and independent tests from industry observers have flagged instances where the filtering for sensitive fields may miss unconventional labels (e.g., nonstandard labels for SSNs), so caution is warranted.
  • Enterprise defaults: Microsoft has suggested Recall is off by default in enterprise deployments and that IT will be able to control its availability; administrators should expect separate policy controls and an opt-in mechanism for recall on corporate devices.
Security implications:
  • New attack surface: Any feature that captures, processes, and indexes screen content increases risk if an attacker can access the snapshot store or exploit the snapshotting logic.
  • Passkey and Windows Hello interactions: The build’s Windows Hello behavior when switching channels highlights potential recovery and key-access complexities. Losing biometric/PIN credentials can have security and availability consequences.
  • Telemetry and diagnostics: As with any preview feature, the telemetry channeling and diagnostic data collection behavior should be audited by privacy-conscious organizations.
Recommendation: Insiders and IT teams should treat Copilot+ features like Recall and Click to Do as sensitive previews — disable or avoid them on machines that process regulated, confidential, or high-risk data until the features mature and enterprise controls are fully documented and tested.

Installation, ISOs, and rollback considerations​

Microsoft released ISOs for Build 27924, which gives testers the choice to perform a clean install rather than updating in-place via Windows Update. Several practical points are critical:
  • ISOs are available for the build — use these if you prefer a clean install or need to reimage devices.
  • Switching channels may require a clean install: You cannot downgrade from Canary to Dev/Beta/Release Preview without reinstalling Windows due to build-number and setup constraints.
  • Back up encryption keys and user data: Before moving a device between channels, ensure you have recovery keys for BitLocker and backups of any local keys or data (particularly if using Recall or other encrypted local stores).
  • Test on secondary hardware: Because Canary builds can introduce regressions that affect boot and sign-in, install the build on test hardware or virtual machines, not production devices.
Step-by-step checklist to install and test safely:
  • Create a full system image and back up important user data to an external location.
  • Export BitLocker recovery keys and document current Windows Hello/credential states.
  • If you want to move off Canary later, plan for an OS clean install and ensure you have installation media ready.
  • Install Build 27924 on a secondary test machine or VM first; validate sign-in, device drivers, and critical apps.
  • Use Feedback Hub aggressively to report crashes, UI issues, and privacy concerns.

Developer and IT admin guidance​

Build 27924 introduces changes that matter to developers and administrators. Here’s a practical distillation:
  • MIDI API breaking change: Recompile and retarget apps that use the preview Windows MIDI API. Expect to update code if m-send semantics changed.
  • File Explorer + version control: Evaluate how File Explorer’s Git integration affects developer workflows. This UI-level integration is convenient, but teams should validate interaction with existing Git tooling and access controls.
  • Test remote desktop and MDM scenarios: The build includes remote desktop fixes but Canary builds can regress other remote work flows. Verify that RDP, VDI, and AVD experiences remain functional before broadly testing.
  • Plan for credential recovery: Document processes to recreate Windows Hello PINs and redeploy biometric factors, especially if team members use Copilot+ features or change channels.
IT admins should also prepare communications for testers that cover:
  • Which devices are permitted for Canary testing.
  • Data-handling expectations for Copilot+ features.
  • Procedures to recover from PIN/biometric issues or to perform clean installs.

Risks and trade-offs — a critical assessment​

Build 27924 represents a classic Canary trade-off: early access to visionary features versus real-world instability and new risk vectors.
Strengths and positive signals:
  • Ambitious AI integrations: By enabling Recall, Click to Do, and local SLMs (small language models) like Phi Silica, Microsoft is moving AI from a web service add-on to a first-class OS capability. This can materially improve productivity and reduce latency for many tasks.
  • Developer ergonomics: Features like File Explorer’s version-control view and the Advanced Settings hub bring developer tools closer to the shell, reducing friction.
  • App improvements: The Snipping Tool’s window-mode recording and ongoing app improvements indicate continued investment in built-in productivity utilities.
Notable risks and weaknesses:
  • Stability: Canary builds are prone to crashes, regressions, and driver incompatibilities. This flight explicitly documents app crashes (dao360.dll) and credential issues.
  • Privacy and filtering gaps: Snapshot-based features like Recall can inadvertently capture sensitive information; filtering is not foolproof, and early tests have shown edge-case leaks.
  • Credential/key fragility: The Windows Hello behavior tied to channel changes and Recall key handling introduces account-recovery complexity.
  • Documentation and policy gaps: Canary flights get limited documentation; enterprises must assume they will need to do their own testing and policy creation before adoption.
  • Support burden: Early adopters should expect to rely on community channels and Feedback Hub rather than formal enterprise support.

Practical recommendations for Insiders and IT teams​

For consumers, power users, and IT pros considering Build 27924, here are concrete, prioritized recommendations:
  • If you rely on your device for work or handle sensitive data, do not install Canary builds on your primary machine.
  • Use a secondary test device or virtual machine for this build. Create VM snapshots so you can rollback quickly.
  • If you plan to try Recall or Click to Do, proactively:
  • Disable snapshot saving where appropriate.
  • Exclude apps or sites that process sensitive information.
  • Test the filter behavior with non-sensitive mock data to understand limitations.
  • For developers, rebuild and test apps that use MIDI services or any experimental platform APIs. Verify runtime behavior on Copilot+ hardware if you target those features.
  • IT admins should:
  • Draft a clear Canary testing policy that includes device eligibility and data-handling controls.
  • Train testers on how to recreate Windows Hello credentials and how to recover from PIN/biometric loss.
  • Test deployment of enterprise management policies to ensure Recall and Click to Do can be disabled or controlled centrally.
  • Report bugs and privacy concerns via Feedback Hub and monitor Flight Hub and Insider channels for follow-up flights.

What to watch for next​

Build 27924 will likely be followed by incremental Canary flights that address Click to Do crashes, the dao360.dll instability, and the Windows Hello credential issue when switching channels. Key items to monitor in subsequent flights:
  • Fixes for Click to Do and Recall behavior — including robustness of sensitive-data filtering and export/reset capabilities for snapshot data.
  • Enterprise policy controls for Copilot+ experiences, enabling admins to opt-in or opt-out centrally.
  • Documentation and SDK updates for APIs affected by the MIDI change and any new runtime model requirements (e.g., Phi Silica runtime).
  • Broader hardware support for Copilot+ beyond initial certified devices, including Arm64EC and additional Intel/AMD devices.

Conclusion​

Windows 11 Insider Preview Build 27924 is an important marker in Microsoft’s roadmap: it surfaces ambitious, on-device AI features and developer-facing settings while reminding testers that Canary is a proving ground, not a production channel. The addition of Recall, Click to Do, and expanded Copilot+ functionality signals a future where the operating system actively assists with context-aware tasks, but those gains come with measurable risks — instability, credential complications, and privacy edge cases.
For enthusiasts and developers eager to explore the bleeding edge, Build 27924 offers a lot to test and critique. For enterprises and users who prioritize stability and security, it reinforces the practical wisdom of validating new platform capabilities through managed pilots, policy controls, and careful risk assessment before broad adoption.

Click to expand...

Today Microsoft pushed Windows 11 Insider Preview Build 27924 to the Canary Channel, and with it a clear signal of where the company is placing its engineering bets: fast-moving platform work coupled with an expanding set of Copilot+ PC experiences (and the trade-offs that come with bleeding-edge testing). The build, published on August 14, 2025, ships ISOs for manual installs and begins enabling a number of Copilot+ features for qualifying devices while also adding a handful of user-facing improvements (notably a redesigned Advanced page in Settings and a new Snipping Tool “window mode” for screen recording). (blogs.windows.com)
What Microsoft released (the short list)
  • Build and channel: Windows 11 Insider Preview Build 27924 — Canary Channel (published August 14, 2025). ISOs are available from Microsoft’s Insider blog post. (blogs.windows.com)
  • Copilot+ experiences: Microsoft begins enabling Recall (Preview), Click to Do (Preview), “Improved Windows Search,” live captions with real‑time translation, and an “agent” inside Settings on Copilot+ PCs (availability is being rolled out gradually and differs by device/region). (blogs.windows.com)
  • Settings: a redesigned Advanced page (Settings > System > Advanced) that consolidates developer-style controls for a broader audience — including Enable long paths (removes MAX_PATH limits), Virtual workspaces (enable/disable Hyper‑V, Windows Sandbox, etc.), and File Explorer + version control (Git metadata displayed inside File Explorer). (blogs.windows.com)
  • Snipping Tool: an update (Snipping Tool version 11.2507.14.0+) introduces a window‑mode recording option so you can record a specific app window with the recording region automatically sized. (blogs.windows.com)
Why this build matters
Microsoft’s Canary Channel is now the place for very early platform work — low-friction checking-in of long‑lead engineering changes — rather than a polished preview of upcoming consumer features. That context matters: Canary builds will include ideas that may never ship publicly, and their quality may trail Dev/Beta channel builds. Build 27924 is noteworthy because it demonstrates two overlapping priorities:
1) Accelerating AI-enabled features on the OS: Microsoft is expanding Copilot+ functionality beyond a single hardware family by enabling features such as Recall and Click to Do on eligible Copilot+ PCs. These features aim to make Windows more “actionable” (search that understands context, quick AI actions on selected text/images, device-level snapshot-based search via Recall). Independent coverage confirms Microsoft is expanding these AI features across Intel, AMD, and Qualcomm Copilot+ hardware and that the rollout is staged and device-dependent. (theverge.com, windowscentral.com)
2) Shipping platform affordances for power users and developers: the Advanced page is effectively a rework of the old “For Developers” area, exposing long-path toggles, virtualization controls, and Git metadata inside File Explorer — the kind of integrations that make the OS friendlier for heavy users and dev workflows. That signals a continued push to make Windows appeal to both creators and developers without needing separate toolchains. (blogs.windows.com)
The big features explained (and what to expect)
  • Recall (Preview): Recall is a local, timeline-style snapshotting tool — it stores device screenshots and event metadata to let you “retrace your steps.” Microsoft emphasizes on-device encryption and Windows Hello authentication for access, but Recall has sparked privacy debates in the past because it stores activity history on the device. The Insider program is being used to stress-test behavior, filtering, and privacy controls before any wider rollout. Coverage of Recall’s staged availability and the privacy conversation is widely documented by outlets that followed Microsoft’s multi-month Insider rollout. (windowscentral.com, tomshardware.com)
  • Click to Do (Preview): This UI/agent layer lets you select on‑screen text or images and perform contextual tasks — summarization, editing, image edits, or “do” actions — through keyboard/mouse shortcuts or the Snipping Tool flow. Microsoft is still ironing out stability and scope (text and image actions can be flaky in early builds), and the Canary release includes known issues that Microsoft expects to fix in upcoming flights. (blogs.windows.com)
  • Improved Windows Search: A retooled search experience intended to use richer semantics and natural language to surface files, settings, and relevant actions. Note that some aspects of Improved Windows Search are being gated (gradual rollout) and may not appear immediately after updating. (blogs.windows.com)
  • Live captions with real‑time translation: Copilot+ PCs get live captioning with translation into target languages; Microsoft has been expanding this capability beyond Qualcomm devices into Intel and AMD Copilot+ hardware. Implementation can be hardware- and market-dependent and has required language/pack work items that some users have reported problems with during early testing. (theverge.com)
Snipping Tool: window-mode screen recording
The Snipping Tool update in this flight adds a useful recording mode: pick Record → Recording area → Window mode, and Snipping Tool will tightly size the capture to a chosen app window. That’s an ergonomically tidy solution for focused recordings (tutorial clips, demos, single-app captures) — but note the recording region is fixed once capture begins (it won’t follow a moving window). This feature is small but practical, and it joins other recent Snipping Tool AI-ish polish Microsoft is adding across insider builds. (blogs.windows.com, windowscentral.com)
Advanced Settings: a quick walkthrough
  • Enable long paths: flips off legacy MAX_PATH limits for many Win32 APIs so deeply nested project trees or long git repo paths don’t break legacy apps that rely on shorter path lengths. (Useful for devs who store large node_modules, nested repos, or deep toolchains.) (blogs.windows.com)
  • Virtual workspaces: toggle virtualization components such as Hyper‑V or Windows Sandbox in one place — helpful for quickly enabling or disabling virtualization features without hunting through “Turn Windows features on or off.” (blogs.windows.com)
  • File Explorer + version control: point File Explorer at a git repository and see branch name, pending diff counts, and last commit messages inline. This is one of the most concrete “developer experience” integrations Windows has added to its file manager in years. (blogs.windows.com)
Known issues and upgrade cautions — read this before you update
Canary Channel builds are explicitly early and potentially unstable. Microsoft lists several known issues in this build; the most impactful ones include:
  • Windows Hello PIN/biometrics loss on some Copilot+ PCs when joining Canary from Dev/Release Preview/retail — error 0xd0000225 (“Something went wrong, and your PIN isn’t available”). In many cases you can recreate the PIN via “Set up my PIN,” but this is disruptive and important to plan for. (blogs.windows.com)
  • Click to Do: text and image actions may fail or Click to Do may crash — Microsoft marked this as a “will be fixed” issue in a future flight. (blogs.windows.com)
  • Underlying dao360.dll problem in this build that may cause some apps to crash; multiple error popups in Group Policy Editor; and other Canary-centric quirks. (blogs.windows.com)
Practical upgrade advice and best practices
If you’re considering this build, follow these rules of the road:
1) Don’t use Canary on your primary production machine. Canary is for experimentation and early feedback, not day-to-day reliability. Back up important data first. (blogs.windows.com)
2) If you need to leave Canary later, expect to perform a clean install of Windows 11 — Microsoft requires a clean installation to move to channels receiving lower build numbers. Plan accordingly. (blogs.windows.com)
3) If you own a Copilot+ PC and migrate to Canary from another channel, be ready to recreate Windows Hello PIN/biometrics. Follow Microsoft’s instructions (Set up my PIN) and, if you manage corporate devices, coordinate with IT. (blogs.windows.com)
4) File feedback aggressively (Feedback Hub, WIN + F, and the GitHub repo called out for Advanced Settings), and upvote relevant issues so Microsoft can triage them faster. The Canary Channel’s purpose is to gather this kind of early feedback. (blogs.windows.com)
Developer and enterprise implications
  • For developers: File Explorer + version control reduces context switching for small Git queries and could speed lightweight repo workflows. But note the Windows MIDI Services change referenced in the build notes — it contains a feedback-driven breaking change that requires apps built against older previews to be recompiled against the latest preview SDKs. If you ship MIDI-related software, update your toolchain and test. (blogs.windows.com)
  • For enterprises: Canary builds are not enterprise-bound releases. IT admins should block Canary enrollment for managed fleet devices and be aware that Copilot+ features (Recall especially) are removed by default from managed or enterprise SKUs; the Recall/Click to Do rollout has privacy and manageability implications that deserve policy review before any larger deployment. Independent reporting shows Microsoft is attempting technical mitigations (TPM encryption, Windows Hello gating) but legal, compliance, and user-privacy teams should be involved before endorsing these features in production. (windowscentral.com, tomshardware.com)
Privacy and ethical considerations (a candid look)
Recall is useful — it’s a local memory timeline — but it’s inherently sensitive because it captures screenshots of activity. Microsoft’s approach has been to keep data local, gate access via Windows Hello, and surface settings to exclude domains and apps, yet the feature remains controversial (and for good reason) because even well-intentioned local capture increases the attack surface and elevates the importance of robust, understandable user controls. Expect feedback-driven adjustments and regional rollout differences (EAAs/EEA timelines may differ). Independent outlets covering the rollout emphasized both the usefulness and the privacy conversation Microsoft must continue to manage. (windowscentral.com, tomshardware.com)
How to try Build 27924 (quick checklist)
  • Join Windows Insider Program and choose Canary Channel (only on devices you can afford to test). Check Settings > Windows Update > Windows Insider Program. (blogs.windows.com)
  • Optionally download the ISO from the Windows Insider post (useful for clean installs or in-place upgrades when Windows Update flighting is delayed). Microsoft included the ISO link in the announcement. (blogs.windows.com)
  • After upgrading, check Settings > System > Advanced for the new Advanced page and Settings > Accessibility / Apps for Snipping Tool updates. If you have a Copilot+ PC, expect features to appear gradually; check the Copilot+ PC guidance (aka.ms/copilotpluspcs) and Microsoft support pages for region/hardware availability. (blogs.windows.com)
Independent corroboration and context
Several respected outlets tracked this wave of AI features and Canary rollouts and corroborate the high-level direction of Microsoft’s changes:
  • Windows Central described Microsoft’s Canary Channel as a place for earlier, riskier platform work and noted the broadened Copilot+ feature set rolling out to more devices. (windowscentral.com)
  • The Verge reported on Microsoft’s expansion of live translation and Copilot+ capabilities to Intel and AMD Copilot+ devices, underscoring the staged rollout and hardware gating that will determine who sees which features and when. (theverge.com)
  • Tom’s Hardware and Tom’s Guide have also written about Recall’s general availability and the surrounding privacy and rollout discussions as Microsoft moved the feature through the Insider program. (tomshardware.com, tomsguide.com)
Bottom line — who should install and who should wait
  • Install if: you’re an Insider who wants to test early platform changes, you have a spare or secondary device for experiments, you are comfortable troubleshooting, and you’ll file concrete feedback. Canary is a place to influence long-lead platform work. (blogs.windows.com)
  • Wait if: this is your main work PC, you depend on full stability, or you’re managing a fleet — Beta/Release Preview (or waiting for Dev/Beta stabilization) is a safer route. Also, organizations and privacy-conscious users should evaluate Recall’s control model thoroughly before permitting deployment on managed devices. (blogs.windows.com, windowscentral.com)
Where to get help and how to provide feedback
  • Report bugs via Feedback Hub (WIN + F). Use the suggested Feedback categories in the blog post for each feature area (Snipping Tool, Click to Do, Copilot+ experiences, Advanced Settings). (blogs.windows.com)
  • Advanced Settings feedback has a dedicated GitHub repo (microsoft/WindowsAdvancedSettings) for issues and feature requests. (blogs.windows.com)
  • Track flights and builds in Flight Hub to see what’s in which Insider channel. (blogs.windows.com)
Final assessment
Build 27924 makes Microsoft’s strategy explicit: keep pushing experimental platform changes rapidly (Canary), use Copilot+ as a way to drive AI-first experiences on qualifying hardware, and fold some developer-oriented conveniences into the OS (Advanced page, File Explorer + Git). For Insiders this is a rich but bumpy release — it contains genuinely interesting productivity tools and developer integrations, but also real stability and privacy questions that require careful testing and, in some cases, policy oversight.
If you plan to test it: back up, use a secondary machine, and be prepared to recreate Windows Hello credentials on some Copilot+ hardware. If you’re watching from an IT or privacy standpoint, this release is an important signal — adopt a cautious, staged evaluation approach. And if you’re curious about specific parts of the build (a deeper walkthrough of File Explorer + Git, a guided Snipping Tool demo, or a privacy checklist for Recall), tell me which one you want first and I’ll write a shorter how‑to or audit checklist with step‑by‑step instructions.

Announcing Windows 11 Insider Preview Build 27924 (Canary Channel) — what to know, what’s new, and whether you should install​

By WindowsForum Staff — August 14, 2025
Microsoft today pushed Windows 11 Insider Preview Build 27924 to the Canary Channel and published ISOs for this flight. The release is notable because it begins enabling several Copilot+ PC experiences in the Canary Channel and adds a redesigned “Advanced” page in Settings that surfaces options such as long-path support, virtual workspace controls, and an integrated File Explorer + version-control view. If you follow Windows Insider releases or run a Copilot+ PC, this build is worth a close look — but it also comes with the normal Canary caveats (instability, limited rollouts, and some known breaking issues). (blogs.windows.com)
This article walks through the major changes, digs into the Copilot+ features that are being enabled, explains the new Advanced settings and Snipping Tool update, summarizes fixes and known issues, and offers practical guidance for Insiders who are thinking of installing Build 27924.
Quick summary (TL;DR)
  • Build: Windows 11 Insider Preview Build 27924 (Canary Channel), published August 14, 2025; ISOs available. (blogs.windows.com)
  • Headline additions: staged enablement of Copilot+ PC experiences (Recall, Click to Do, Improved Windows Search, Live captions with translation, Agent in Settings), new Advanced Settings page (Enable long paths, Virtual Workspaces, File Explorer + Version Control), and a Snipping Tool update with window-mode screen recording. (blogs.windows.com)
  • Channel guidance: Canary builds are experimental platform workstreams. Expect rough edges; a clean install is required to move back to a lower-numbered channel. (blogs.windows.com)

What Microsoft is enabling in this flight: Copilot+ PC experiences​

One of the central announcements in Build 27924 is that Microsoft has started to enable a collection of Copilot+ PC features for Canary Insiders who have Copilot+ PCs. The blog post lists the following experiences being turned on (gradually and by device/market): Recall (Preview), Click to Do (Preview), Improved Windows Search, Live captions with real-time translation, and an “Agent in Settings.” (blogs.windows.com)
Why this matters
  • These features are part of Microsoft’s Copilot+ PC strategy: device hardware and firmware combined with local+cloud AI models to provide richer, contextual experiences (for example, searchable local snapshots of activity via Recall). The goal is to deliver next‑generation productivity tools that leverage device-resident AI while respecting local security boundaries on Copilot+ certified hardware. (blogs.windows.com, tomshardware.com)
Short explainer of the major Copilot+ features mentioned
  • Recall (Preview): A local snapshot/timeline interface that captures and indexes images and activity on your PC so you can “retrace your steps” or search for what you did by describing it (e.g., “that chart I edited last week”). Recall is opt-in, encrypts snapshots locally, and requires Windows Hello/TPM/BitLocker checks during setup. Microsoft emphasizes that the snapshot data is stored locally and not used for training Microsoft models. Recall has been tested in Insider channels previously and now begins to be enabled more widely on Copilot+ devices. (blogs.windows.com)
  • Click to Do (Preview): Contextual actions you can take on text and images (summarize, edit, extract, etc.). Microsoft has previously rolled Click to Do previews in Insider rings; the implementation is being expanded but remains a work in progress and may be device-bound at first. (blogs.windows.com)
  • Improved Windows Search: An AI-enhanced search experience that uses natural language and richer ranking to help you find files, screenshots, and content across local snapshots and indexed content. Rollout is being done gradually. (blogs.windows.com)
  • Live captions with real-time translation and “Agent in Settings”: Microsoft is enabling additional accessibility and assistant-style experiences. These are being ramped using feature rollouts, so availability may vary. (blogs.windows.com)

Privacy, security, and earlier concerns (what to watch)​

Because Recall and related snapshot features capture local activity, they have attracted attention around privacy and security since their first previews. Microsoft’s approach in preview emphasizes opt‑in, local encryption (TPM/Windows Hello), and filters to avoid saving sensitive information such as credit cards and passwords. Recall’s ability to index visual content locally is powerful, but it also requires careful opt-in and appropriate safeguards — which Microsoft has repeatedly highlighted in its Insider documentation and in prior coverage. If these protections matter for you, make sure to read and configure Recall’s options in Settings and only opt in after validating BitLocker, Windows Hello, and other preconditions. (blogs.windows.com, tomshardware.com, theverge.com)
Note: Recall originally appeared in Dev-channel previews and received media coverage and follow-up security hardening before being rolled out more broadly to Copilot+ PCs; if you missed the earlier coverage, see Microsoft’s Recall preview posts and third-party reporting for additional context. (blogs.windows.com, theverge.com)

Advanced Settings: a clearer home for developer and platform controls​

Build 27924 introduces a redesigned Settings page at Settings > System > Advanced. It replaces or broadens the old “For developers” area with a more discoverable layout and includes a few notable controls:
  • Enable long paths — removes the historical MAX_PATH limitations for legacy Win32 functions (useful for developers and power users who work with deep folder trees). Microsoft links to documentation about MAX_PATH and how this setting interacts with APIs and registry/behavior. (blogs.windows.com)
  • Virtual Workspaces — a central switch to enable/disable virtual environment capabilities such as Hyper-V, Windows Sandbox, and related virtualization services. This makes it quicker to toggle virtualized features without digging into separate Windows Features dialogs. (blogs.windows.com)
  • File Explorer + Version Control — a UI surface that shows Git repository metadata directly in File Explorer: branch name, diff counts, last commit message, and other repository cues for selected folders. If you use Git in local folders, this will be the most immediately visible productivity improvement in the Advanced page. (blogs.windows.com)
Microsoft has also directed feedback for the Advanced page to a GitHub repo (microsoft/WindowsAdvancedSettings), so power users and developers can file requests or follow the feature’s progress there. (blogs.windows.com)

Snipping Tool update: window-mode screen recording​

The Snipping Tool gets a functional update in this flight (version 11.2507.14.0 and higher rolling out to Canary and Dev channels). The headline: a “window mode” recording option in the Record toolbar that lets you select a specific application window as the recording region; Snipping Tool will size the capture region to the chosen app. The recording area remains fixed once you begin capturing (it won’t follow a window if you move it), so this is a targeted, easy way to make focused recordings of a single app without manual cropping. (blogs.windows.com)

Fixes and stability notes​

Build 27924 includes a set of smaller fixes called out by Microsoft:
  • UI fix for progress wheel glyph rendering during upgrades. (blogs.windows.com)
  • Widgets disappearance bug fixed for some Insiders. (blogs.windows.com)
  • Remote Desktop: fixed an issue where RDP sessions used only the primary monitor despite multi-monitor selections. (blogs.windows.com)
  • Underlying webauth.dll crash addressed (which may have impacted passkeys behavior). (blogs.windows.com)

Known issues you should not ignore​

Because this is a Canary build, Microsoft lists a handful of important and potentially disruptive issues:
  • IMPORTANT for Copilot+ PCs: If you join the Canary Channel on a new Copilot+ PC from Dev, Release Preview, or retail, you may lose Windows Hello PIN and biometric sign-in with an error 0xd0000225 (“Something went wrong, and your PIN isn’t available”). You should be able to recreate your PIN by using “Set up my PIN” after the upgrade, but losing your enrolled biometrics or PIN temporarily is disruptive — plan ahead and ensure you have a fallback sign-in method. (blogs.windows.com)
  • Group Policy Editor may show multiple unexpected error popups in some cases. (blogs.windows.com)
  • An underlying dao360.dll problem in this build may cause some apps to crash. Expect to see app instability in affected configurations. (blogs.windows.com)
  • Click to Do (Preview) known regression: text and image actions may not work and Click to Do may crash; Microsoft says this will be fixed in the next flight. If Click to Do is a primary reason you want to test this build, be prepared for broken behaviors. (blogs.windows.com)

Who should (and shouldn’t) install Build 27924​

Install if:
  • You are an advanced Insider who understands Canary-level risk and likes testing experimental platform changes. (blogs.windows.com)
  • You own a Copilot+ certified PC and want to test Recall/Click to Do/Improved Search as these features become enabled. Be prepared to file feedback via Feedback Hub. (blogs.windows.com)
  • You are a developer or power user interested in the new Advanced Settings and the File Explorer + version-control integration. (blogs.windows.com)
Avoid installing if:
  • You rely on this PC for critical or production tasks (work, school, or client systems) — Canary builds are experimental and can break things like sign-in or essential apps. (blogs.windows.com)
  • You are not comfortable troubleshooting rollbacks and are not prepared to do a clean install if you later want to move to a lower-numbered Insider channel (Canary -> Dev/Beta/Release Preview or retail requires a clean install in some scenarios). (blogs.windows.com)

How to get Build 27924 (and where Microsoft points you)​

  • If you’re already in the Canary Channel, check Windows Update to receive the build. Microsoft is also providing ISOs for this flight (the blog links to aka.ms/wipISO for downloads). If you prefer a clean install or want to set up a test machine from scratch, the ISOs are the recommended way. (blogs.windows.com)
  • Flight Hub is the official place to check which builds are in which Insider channels; Microsoft reminds Insiders to consult Flight Hub for the full rollout picture. (blogs.windows.com)

Practical tips before you install​

  • Back up everything. Use a full image or at least File History / OneDrive for critical files. Canary builds can require troubleshooting or a clean reinstall. (blogs.windows.com)
  • If you have a Copilot+ PC and care about Windows Hello, ensure you have a fallback sign-in or the ability to re-create your PIN (and know your Microsoft account password). The blog calls out a temporary PIN/biometric loss scenario for some Copilot+ upgrades. (blogs.windows.com)
  • If you want Recall but are worried about privacy, don’t opt in until you’ve read the Recall settings and understand BitLocker / TPM / Windows Hello prerequisites; the feature is opt‑in and Microsoft has added filters to avoid storing some sensitive data types. For historical context on Recall previews and Microsoft’s stated safeguards, see Microsoft’s Recall preview documentation and early reporting. (blogs.windows.com, theverge.com)
  • Use a test machine or VM where possible; Canary flights are intended for exploratory testing and concept validation. (blogs.windows.com)

How to provide feedback​

Microsoft asks Insiders to file feedback via Feedback Hub for Copilot+ experiences, Snipping Tool, and other preview features. For the Advanced Settings feature, Microsoft specifically directed feedback to the microsoft/WindowsAdvancedSettings GitHub repository. If you encounter crashes or data loss, include repro steps and diagnostics in your Feedback Hub reports. (blogs.windows.com)

Context & background: how we got here​

Recall, Click to Do, and other Copilot+ experiences have been in development and Insider previews for months. Microsoft first previewed Recall and Click to Do to Insiders in earlier Dev-channel flights and iterated on security and privacy controls after community feedback. Third-party reporting (The Verge, Tom’s Hardware) tracked the preview, the opt‑in model, and Microsoft’s efforts to address privacy concerns. The start of a broader Canary rollout in Build 27924 is an expected next step in Microsoft’s measured preview process. (blogs.windows.com, theverge.com, tomshardware.com)

Bottom line​

Build 27924 is a Canary-level release that marks another step toward making Copilot+ PC experiences available to more Insiders. It also introduces practical productivity features — the Advanced Settings redesign and Explorer + Git cues should be useful for developers. That said, Canary = experimental; there are known regressions (including a potentially disruptive Windows Hello PIN/biometric issue on Copilot+ upgrades) and other reliability problems. If you like to test bleeding-edge platform changes and you’re running a spare or non-critical Copilot+ PC, it’s worth installing and filing feedback. If this machine is essential, wait for these capabilities to stabilize in Dev/Beta or a production release. (blogs.windows.com, tomshardware.com)

Microsoft has pushed Windows 11 Insider Preview Build 27924 to the Canary Channel, shipping ISOs and beginning a staged enablement of several Copilot+ PC experiences alongside a redesigned Advanced settings hub and a targeted Snipping Tool update — a release that signals Microsoft’s push to put more AI-driven capabilities and developer ergonomics into the OS while also underscoring the practical and security trade-offs of testing on Canary-tier builds. (blogs.windows.com)

Background​

Microsoft’s Canary Channel is explicitly the earliest public outlet for platform-level experimentation; builds here can contain high-impact changes, API breakage, or features that may never ship broadly. Build 27924 follows that pattern: it introduces several Copilot+ experiences in preview, exposes new system-level toggles aimed at developers and power users, and delivers an app-level improvement to Snipping Tool’s recording workflow. The company warns that feature rollouts are gradual, that not all Copilot+ functions will appear immediately on every qualifying device, and that Canary stability may trail Dev and Beta channel quality. (blogs.windows.com)
This flight is notable because it does two things at once: (1) expands the footprint of on-device AI capabilities marketed under the Copilot+ PC initiative, and (2) consolidates developer-oriented controls into a more discoverable Settings surface. That combination — user-facing AI features plus platform-level toggles and breaking API notes — makes this an especially meaningful Canary release for testers, developers, and IT teams. (thurrott.com)

What’s new in Build 27924 — at a glance​

  • Copilot+ PC experiences beginning staged rollouts: Recall (Preview), Click to Do (Preview), Improved Windows Search, live captions with real-time translation, and an agent in Settings. Availability is device- and market-dependent and being ramped slowly. (blogs.windows.com)
  • Advanced Settings: a redesigned Settings > System > Advanced page (replacing the For Developers page) that includes toggles for Enable long paths, Virtual workspaces, and File Explorer + version control (Git metadata shown in Explorer). (blogs.windows.com)
  • Snipping Tool update (version 11.2507.14.0 and higher rolling to Canary and Dev) adding window-mode screen recording that sizes the capture to a chosen app window (region is fixed once recording starts). (blogs.windows.com)
  • Miscellaneous input and service changes: a tweak to the pointer-indicator appearance and a temporary shortcut change to reduce accidental invocation; a breaking change in the preview Windows MIDI Services that requires recompile against the latest preview SDK. (blogs.windows.com)
  • Fixes and a non-trivial set of known issues, including a potentially disruptive Windows Hello PIN/biometric loss when migrating Copilot+ PCs into Canary (error 0xd0000225) and a dao360.dll-related instability that may cause app crashes. (blogs.windows.com)
At least two reputable outlets and several community trackers reported and contextualized these points in parallel with the official post, confirming the presence and staged nature of Copilot+ enablement and highlighting the same stability and privacy cautions. (windowscentral.com, thurrott.com)

Deep dive: Copilot+ PC experiences​

What Microsoft is enabling​

Build 27924 begins enabling a set of Copilot+ experiences on qualifying Copilot+ PCs. The named experiences in the announcement are:
  • Recall (Preview) — a local snapshot-and-search system that captures visual activity and metadata so users can “retrace steps” across apps, files, and web content.
  • Click to Do (Preview) — an on-screen contextual action layer that offers actionable operations on selected text and images (summarize, edit, extract, follow-up Copilot actions).
  • Improved Windows Search — AI-enriched search designed to understand natural language and index richer content (including local snapshots).
  • Live captions with real-time translation — expanded live-captioning that can translate spoken content in real time.
  • Agent in Settings — a Copilot-style assistant surfaced inside the Settings app to help locate and apply configuration options.
These features are explicitly rolling out gradually and are gated by device capabilities and market availability; Insiders on Copilot+ PCs should not expect immediate, universal access after updating. (blogs.windows.com)

Why this matters​

Putting features like Recall and Click to Do into the OS itself changes user expectations. Instead of opening separate apps for OCR, summarization, or screenshot archives, Windows is being positioned as a contextual productivity layer that can surface actionable intelligence directly atop the desktop. For power users, that reduces friction. For organizations, it raises important questions about control, auditability, and data governance. Independent reporting on earlier Recall previews and rollouts documents the same trade-offs: capability vs. control. (tomshardware.com, elevenforum.com)

Privacy and security posture​

Microsoft frames Recall as opt-in and protected by local encryption tied to TPM and Windows Hello, with filters intended to avoid saving highly sensitive content like passwords or credit card numbers. Those safeguards reduce some risks but do not eliminate them: storing visual snapshots of desktop activity on a device increases the attack surface and raises compliance questions — especially on shared or managed endpoints. Admin controls, local retention policies, and the ability to centrally disable or manage these features are critical for enterprise adoption. Third-party coverage and community analysis stress that IT teams should treat Recall as a policy and process project, not just a product-side toggle. (tomshardware.com)

Current limitations and warnings​

  • Functionality is hardware- and model-dependent; early device support focused on Copilot+ certified hardware and certain processors. Expect platform gating and phased availability. Some features (image descriptions for Narrator, certain Click to Do actions) are still being enabled in follow-up flights. (blogs.windows.com)
  • Stability caveats: Microsoft explicitly notes Canary quality will lag other channels; Click to Do is called out as flaky in this flight (text and image actions may not work and Click to Do may crash). (blogs.windows.com)

Advanced Settings: a settings redesign aimed at power users and developers​

What's changed​

The new Settings > System > Advanced page replaces the prior For Developers UI and collects several platform toggles in a more discoverable place. Primary additions:
  • Enable long paths — removes the historical MAX_PATH limitation that affects legacy Win32 file and directory calls.
  • Virtual workspaces — a central control to enable/disable virtualization-related features like Hyper‑V and Windows Sandbox.
  • File Explorer + version control — a File Explorer integration that surfaces Git repository metadata (branch name, diff counts, last commit message) for local repositories. (blogs.windows.com)

Practical benefits​

For developers and creators, this change is a usability win: File Explorer surfacing Git info reduces context switching; toggles for long paths eliminate common headaches when working with deep project trees; a single place to flip virtualization capabilities simplifies testbed setup. These are small but practical productivity improvements that move common workflows into the OS shell.

Enterprise considerations​

The changes raise key questions for managed environments: how do these toggles map to MDM/Group Policy? Will IT admins be able to enforce long-path behavior, lock down Recall/Click to Do, or prevent File Explorer from exposing repository metadata on corporate machines? Microsoft has pointed Advanced Settings feedback to a GitHub repo for the feature, which suggests a degree of community-driven iteration, but organizations should await formal policy documentation before enabling broad deployments. (blogs.windows.com)

Snipping Tool: window-mode screen recording​

What’s new​

Snipping Tool version 11.2507.14.0 and higher rolling to Canary and Dev adds a window-mode screen recording option. In the Record toolbar, choose Recording area → Window mode, then pick an app window; Snipping Tool will size the capture to the app window and start recording. The capture region is fixed for the session — if the window moves or is occluded, the recording does not follow. (blogs.windows.com)

Why this matters​

The new mode simplifies ad-hoc, app-focused recordings without manual cropping or later editing. For quick demos, how-tos, or bug repro videos that only need a single, steady window capture, this reduces friction and keeps builds and content creation inside the OS. Independent hands-on reports and community threads highlight this as a practical, user-visible upgrade. (elevenforum.com)

Limitations​

  • The region is static; dynamic window movement is not tracked.
  • The update is rolling out to insiders in staged fashion; not every Insider will see it immediately. (blogs.windows.com)

Other notable changes and developer impact​

  • Pointer indicator tweak and shortcut change: the pointer indicator was made slightly more transparent for better visibility, and the shortcut changed from Ctrl + Win + X to Ctrl + Win + Alt + X to reduce accidental activation in this flight. (blogs.windows.com)
  • Windows MIDI Services: the inbox preview MIDI Service and API introduced a feedback-driven breaking change that optionally waits for messages to be fully sent before returning from calls. Apps built against earlier preview versions must be recompiled against the latest preview SDK available via the MIDI releases channel and potentially updated for the new semantics. Microsoft also directed the MIDI community to a Discord server for discussion. This is a concrete example of Canary-level platform evolution that can require developer action. (blogs.windows.com)
  • Fixes: progress wheel glyph rendering on upgrade, widgets disappearing for some Insiders, RDP multi-monitor issues, and an underlying webauth.dll crash affecting passkeys were addressed in this flight. (blogs.windows.com)

Known issues and real risks (what to watch for)​

Build 27924 contains a handful of high-friction known issues Insiders should weigh carefully:
  • Windows Hello PIN/biometric loss on Copilot+ PCs when switching channels: If you join Canary on a Copilot+ PC from Dev, Release Preview, or retail, you may temporarily lose Windows Hello PIN and biometrics and encounter error 0xd0000225 (“Something went wrong, and your PIN isn’t available”). Microsoft says you should be able to re-create the PIN via “Set up my PIN”, but this disruption is significant for those who rely on biometric sign-in. (blogs.windows.com)
  • dao360.dll instability: an underlying issue may cause some apps to crash on affected systems. (blogs.windows.com)
  • Click to Do regressions: text and image actions may not work; Click to Do can crash in this build. Microsoft expects fixes in a follow-up flight, but testers should be prepared for broken behavior. (blogs.windows.com)
  • Group Policy Editor pop-ups: users may see multiple unexpected error pop-ups when opening the editor on some systems. (blogs.windows.com)
Collectively these issues underscore why Canary remains a testing ground: use it on a secondary machine only, and expect to perform troubleshooting or a clean install if you later need to switch to a lower-numbered channel. Several community write-ups and forum threads reiterate this advice and provide hands-on notes from early installs. (elevenforum.com)

Privacy and compliance analysis — a closer look at Recall​

Recall is the feature most likely to attract scrutiny. It offers powerful convenience — the ability to search past visual states and find things you previously worked on — but it also records screenshots and activity metadata on the device. Key points for privacy-conscious users and IT teams:
  • Opt-in by design: Recall requires user opt-in before capturing activity. Microsoft emphasizes that snapshots are encrypted locally, protected by TPM and Windows Hello, and subject to filters designed to avoid capturing known sensitive data.
  • Attack surface: Storing visual snapshots on the device means an adversary who can bypass OS protections or compromise disk encryption could potentially access sensitive captures. BitLocker/TPM setup and solid endpoint defenses become more important when Recall is enabled.
  • Policy and manageability: Enterprises should require vendor-provided MDM/Group Policy entries for controlling Recall and Click to Do, define retention policies, and test the features under their compliance rules. Until those controls are fully documented, conservative teams should block Canary enrollment for managed devices.
  • Transparency and user education: Even with safeguards, users need clear, understandable settings describing what’s captured, retention windows, and how to purge data. Prior Insider discussions and media coverage show that adequate education materially affected user sentiment toward Recall. (tomshardware.com)
Where Microsoft’s public claims (local-only storage, encryption, filters) are auditable, organizations should validate those claims in a controlled lab, test edge cases (screens with mixed sensitive and non-sensitive content), and seek documentation of retention controls and forensic behavior before deploying at scale.

Practical guidance: who should install, and a preflight checklist​

This build is appropriate for advanced Insiders, developers, and testers who understand Canary stability risks. It is not recommended for production or primary work devices.
If you decide to test Build 27924, follow these steps:
  • Back up everything: create a full disk image and/or ensure critical documents are synced to a reliable cloud or offline backup.
  • Use a spare machine or VM where possible — do not use your daily driver.
  • Note that moving off Canary to a channel with a lower build number may require a clean install; plan accordingly. (blogs.windows.com)
  • If you own a Copilot+ PC and plan to migrate channels, ensure you have alternative sign-in credentials and are prepared to re-create Windows Hello PIN/biometrics. Keep your Microsoft account password handy. (blogs.windows.com)
  • For IT teams: block Canary enrollment on managed devices, prepare policy controls, run lab tests for Recall and Click to Do, and document MDM/Group Policy approaches for when features mature.
A short checklist before upgrading:
  • Create system image and recovery media.
  • Export BitLocker recovery keys and ensure TPM is functional.
  • Verify that you can sign in with a Microsoft account password if Windows Hello fails.
  • Prepare to file detailed repro and diagnostics in Feedback Hub (WIN + F) for any Copilot+ or Snipping Tool issues.

Enterprise implications and developer action items​

For enterprise IT:
  • Treat Canary builds as not for production. Develop a formal Insider testing policy and maintain a segregated test fleet.
  • Evaluate Recall and Click to Do as features that require policy controls and potential legal review (data retention, privacy, and disclosure concerns).
  • Monitor Microsoft’s documentation for formal Group Policy/MDM controls and update device hardening checklists accordingly.
For developers:
  • Recompile and test any MIDI-aware apps against the latest Windows MIDI Services preview SDKs — the flight includes a breaking change in the preview MIDI API semantics that can cause runtime issues. Microsoft advised recompile and linked to the MIDI preview releases. (blogs.windows.com)
  • Watch for API and behavior changes in Canary that may cascade into Dev/Beta in future flights. Use feature-detection and graceful degradation where possible.

Verdict: why this flight matters — and how to treat it​

Build 27924 is a strong signal of Microsoft’s priorities: accelerate on-device AI experiences while polishing platform affordances for developers and creators. The conceptual advances — integrating Git metadata into Explorer, making long-path toggles visible, and seeding Copilot+ features across more hardware — point toward a Windows that is both more assistive and more developer-friendly.
That said, the practical considerations are unambiguous: Canary is experimental. The PIN/biometric disruption, Click to Do instability, dao360.dll crashes, and the MIDI SDK breaking change are all real, testable risks that justify a conservative approach for any production user or managed fleet. The correct posture is to test aggressively in lab and pilot contexts while keeping production devices on Dev/Beta/Release Preview or retail builds until features and policies stabilize. (blogs.windows.com)

Final takeaways​

  • Build 27924 is an important developer- and AI-focused Canary release that begins enabling Copilot+ experiences in preview, introduces a useful Snipping Tool window-mode recording, and consolidates developer controls into a redesigned Advanced Settings page. (blogs.windows.com)
  • The release underscores the tension between rapid innovation and manageability: features like Recall and Click to Do are promising but require careful privacy and policy review before broad adoption. Independent outlets and community trackers corroborate these findings and emphasize the same cautions. (windowscentral.com)
  • Practical guidance: test on a spare machine, back up first, expect to recreate Windows Hello credentials on some Copilot+ hardware, and for enterprises, block Canary on managed devices until Microsoft publishes formal management controls and documentation.
Build 27924 is a fertile preview of a Windows that wants to be more helpful and more integrated with developer workflows; it’s also a reminder that the path to those capabilities must be paved with clear controls, robust documentation, and disciplined testing.
