Windows 11 Build 26120.5770 Adds Copilot‑Centric Productivity Features

Microsoft has pushed a targeted Beta‑channel update for Windows Insiders — Windows 11 Insider Preview Build 26120.5770 (KB5064089) for devices on the Windows 11, version 24H2 servicing baseline — rolling out a batch of Copilot‑centric productivity features, accessibility enhancements, and a slate of stability fixes that are being staged progressively to testers.

Background​

Windows Insider Beta builds in the 26120 series act as a near‑final proving ground for features Microsoft hopes to ship broadly to 24H2 users. Microsoft delivers these updates in an enablement and cumulative model where some features are gradually rolled out (server‑side gated) to a subset of Insiders who opt into the “get the latest updates” toggle, while other quality fixes deploy generally to all Beta devices that install the package. That delivery model reduces the blast radius for early regressions while allowing telemetry and feedback to guide feature exposure.
This build continues Microsoft’s focus on embedding Microsoft 365 and Copilot experiences into the Windows shell — most visibly via Click to Do — and adds an accessibility‑focused Braille viewer in Narrator alongside practical sharing and platform parity fixes. The rollout strategy intentionally gates the most advanced on‑device AI features to Copilot+ certified hardware initially and applies regional and licensing restrictions for certain capabilities.

What’s new in Build 26120.5770​

Click to Do: “Convert to table with Excel” — a practical capture‑to‑spreadsheet action​

The headline user‑facing addition is a new text action for Click to Do: Convert to table with Excel. Click to Do can now attempt to detect simple on‑screen table layouts (from documents, screenshots, shared Teams content, photos, and other rendered sources), highlight that area, and offer an action that converts the capture into an editable Excel table. The converted data can be sent directly to Excel, copied to the clipboard, or shared through the usual channels — eliminating much manual transcription.
Key practical points:

• Invocation supports the standard Click to Do gestures: Win + Click, Win + Q, or touch gestures.
• The feature is explicitly early preview — detection accuracy favors simple rectangular grids; complex tables with merged cells, nested headers, embedded images, or non‑uniform spacing may produce imperfect results. Expect iterative accuracy improvements in future Insider flights.
• Early access is being tested first on Snapdragon‑powered Copilot+ PCs; Microsoft states Intel and AMD Copilot+ support is coming soon. The rollout is server‑side gated, so having the Beta build installed does not guarantee immediate exposure.
• An active Microsoft 365 subscription and the latest Microsoft Excel app are required for the full end‑to‑end experience; the captured conversion ties into Microsoft 365 entitlements.
• The capability is currently withheld in certain regions (initially not available to Insiders in the European Economic Area) while Microsoft addresses regional considerations.

How the workflow looks in practice:

• Invoke Click to Do over the screen area containing a table.
• Use the selection mode (rectangle, freeform, or multi‑select) to highlight the table.
• Select “Convert to table with Excel” from the Click to Do action list.
• Send to Excel, copy the resulting table, or share it. Once in Excel, the data behaves like a native table for sorting, filtering, and formulas.

This feature is a clear productivity win for knowledge workers and educators who frequently transcribe meeting slides, shared calendars, or screenshoted tables — but it comes with practical constraints (licensing, hardware gating, and detection quality) that will influence early adoption.

Microsoft 365 Profile (Live Persona) cards inside Click to Do​

Click to Do now recognizes organizational email addresses and can surface a Microsoft 365 profile card (Live Persona) inline, giving quick access to contact details, recent collaboration context (files and messages), and actionable links (call/chat/email) without switching apps. This reduces context‑switching for enterprise users who often open Outlook or Teams to look up colleagues.
Requirements and caveats:

• Must be signed in with a work or school (Entra ID) account.
• Requires a Microsoft 365 subscription on the account to surface the full persona data.
• Like table conversion, the feature is being roll‑out gated and may not be visible to all Insiders immediately.

Narrator: on‑screen Braille viewer — a visibility tool for AT workflows​

Narrator gains a Braille viewer, a floating window that mirrors the textual and Braille output from a connected refreshable Braille display, or shows a default 40‑cell fallback when no hardware is attached. The viewer updates in real time, can be repositioned, and allows changing the displayed cell count. It’s explicitly targeted at sighted teachers, assistive‑technology trainers, developers, and testers who may need to see Braille output visually for instruction, verification, or debugging.
Accessibility team note: the feature reduces test friction when a physical Braille display is unavailable and improves classroom visibility so instructors can confirm what students with visual impairments receive from screen readers.

Windows Share: Find Apps and share‑sheet refinements​

The Windows share dialog now includes a Find apps option that searches installed apps and suggests Microsoft Store results directly within the share UI, streamlining the process of routing content to less‑commonly used apps without leaving the share surface. This is a small but welcome workflow polish for power users who share content frequently.

Under‑the‑hood: Direct3D/Agility SDK parity and platform fixes​

Build 26120.5770 aligns the OS version of Direct3D 12 with the Agility SDK 1.616.1 contents — an important parity step for game and graphics developers who rely on SDK alignment across development environments. The build also includes fixes for HDR toggles, taskbar preview thumbnails, windowing crashes, and audio recovery scenarios.

Fixes, known issues, and rollout behavior​

This flight blends staged feature exposure with a broad set of targeted fixes. Microsoft enables many of these fixes for Beta Insiders who have opted into the gradual rollout; others apply more broadly.
Notable fixes included:

• Taskbar and system tray behavior corrections (date/time flyouts, duplicate preview thumbnails).
• Windowing and Explorer stability patches (ALT+Tab‑triggered explorer.exe crash fix).
• Display/HDR fixes where HDR could toggle off unexpectedly.
• Audio issues, including resolution for audio stopping after casting to a TV.

Known issues you should weigh before installing:

• Settings > System > Storage: the Temporary files scan may get stuck for some users.
• Audio driver anomalies have been reported where certain audio devices show yellow exclamation marks in Device Manager and fail to load — manual driver updates are suggested as a workaround.
• Bluetooth Xbox controller usage produced bugchecks for some Insiders in earlier flights; Microsoft documented a Device Manager workaround (uninstall the OEM XboxGameControllerDriver.inf) until an official fix arrives. This is a severe class of issue (bugcheck), so Insiders relying on Bluetooth controllers should be cautious.
• File Explorer’s Shared section may appear empty in some cases.

Operational rollout notes:

• Feature exposure is controlled via server‑side flags; installing the KB does not guarantee immediate access to the new Click to Do actions or other gated experiences. Insiders who want the earliest exposure should enable the “get the latest updates” toggle in Windows Update settings, but that increases exposure to experiments and potential regressions.

Enterprise and IT implications — what to test and prepare for​

The 24H2/26120 servicing model and the Copilot‑centric feature set introduce several practical concerns for IT and device managers:

• Licensing and entitlements matter. Several new capabilities (Convert to table with Excel, Live Persona cards) require Microsoft 365 subscriptions and, in some Copilot scenarios, specific Copilot licensing. IT must inventory user licensing before enabling broad access.
• Copilot+ hardware gating. The most advanced on‑device AI experiences are being staged for Copilot+ certified PCs (initially Snapdragon NPU devices). If your organization plans to test the full Copilot+ stack, verify hardware requirements and NPU capabilities for your device estate. Some community notes reference NPUs rated for 40+ TOPS as part of Copilot+ guidance; treat those numbers as indicative of a high‑performance NPU requirement and verify with vendor specs for your hardware.
• Driver and agent compatibility. Insider flights occasionally surface regression windows for drivers, EDR/AV agents, and management tools. Test critical endpoints (backup, antivirus, management agents, storage drivers) in a controlled pilot before wide deployment.
• Automation and legacy tooling. Review scripts and automation that rely on deprecated components (for example, PowerShell 2.0 or WMIC). Microsoft has signaled deprecation moves that may affect recovery or management scripts; reauthor any WMIC/PSv2 workflows with modern PowerShell or supported APIs.

A short IT pilot checklist:

• Target a small, non‑production pilot group and enable the Beta channel on test devices only.
• Verify Microsoft 365 licensing for pilot user accounts and confirm Excel client versions.
• Confirm Copilot+ hardware status for any devices that need to exercise on‑device AI features.
• Test critical peripherals (Bluetooth audio/headsets, Xbox controllers, display/HDR workflows).
• Monitor Feedback Hub reports and Microsoft’s Flight Hub for fixes or rollback advisories.

Accessibility impact — practical benefits and considerations​

The Narrator Braille viewer is an important accessibility investment. By providing a visible mapping of Braille output, it helps sighted instructors and developers validate what students and AT users actually receive. This reduces the need for shared physical devices in training and demonstrates Microsoft’s attention to inclusive feature design.
Potential follow‑ups and considerations:

• Validate how the Braille viewer behaves with a variety of refreshable Braille displays and different cell counts. The viewer supports a fallback 40‑cell display when no hardware is attached, but real‑world parity should be confirmed across devices.
• Ensure training materials and AT workflows are updated to include the viewer as a diagnostic tool — it will be particularly useful in classroom and lab environments where sighted staff need to verify student output quickly.

Security, privacy, and governance considerations​

Embedding tenant‑aware productivity primitives into the OS shell brings real governance implications:

• Data flows and Microsoft 365 integration. Convert to table and Live Persona cards rely on Microsoft 365 entitlements and Graph data. IT teams should assess tenant policies, data residency, and conditional access rules to avoid unintended data exposure or cross‑tenant leakage. Organizations with strict data governance requirements should validate how captured screen content is processed and stored.
• Regional and regulatory gating. The feature’s initial withholding in the European Economic Area underscores that Microsoft is considering regional privacy and compliance constraints. Expect Microsoft to continue using regional gating where necessary.
• Auditing and telemetry. Because Click to Do actions may invoke cloud services, confirm audit logging and monitoring are configured for tenant administrators who want visibility into usage and potential data exfiltration patterns.

Flagging unverifiable or evolving claims:

• The precise NPU performance threshold that defines Copilot+ hardware (specific TOPS figures or NPU models) is sometimes discussed in community summaries; organizations should verify exact hardware requirements per vendor documentation and Microsoft’s official Copilot+ hardware guidance before purchasing decisions. Treat community TOPS numbers as directional until validated with manufacturer/specification documents.

How to get the build, enable features, and report issues​

Getting Build 26120.5770:

• Join the Windows Insider Program and opt into the Beta Channel.
• In Windows Update, enable the “Get the latest updates as they are available” toggle to maximize your chance of seeing controlled feature rollouts, understanding that this increases exposure to staged experiments.

Reporting problems and providing feedback:

• Use the Feedback Hub to report functional issues and feature expectations; Microsoft actively monitors Insider feedback to triage regressions and iterate features.

Troubleshooting a few known regressions:

• If you encounter a rollback (0x80070005 or similar) during install, try Settings > System > Recovery and use the “Fix issues using Windows Update” option; Microsoft continues to track install rollback cases.
• For Xbox controller bugchecks tied to Bluetooth, the community workaround is to uninstall the OEM XboxGameControllerDriver.inf driver from Device Manager until Microsoft ships a fix. Use caution — bugchecks are severe and indicate you should avoid Beta builds on critical machines if you depend on that hardware.
• If Device Manager shows audio device yellow exclamation marks, try manual driver updates from the vendor or roll back recent driver changes until a platform fix arrives.

Critical analysis — strengths, risks, and what to watch​

Strengths

• Practical productivity gains. The Click to Do Convert to table with Excel action addresses a common, time‑consuming task: transcribing tabular data from visual artifacts into spreadsheets. For teams that handle meeting outputs, receipts, or scheduling captures, this can reduce friction and human error.
• Accessibility progress. The Narrator Braille viewer is a meaningful, low‑friction tool that improves training and testing workflows for assistive technology. It is the kind of incremental accessibility improvement that has immediate classroom and developer value.
• Iterative, gated rollout minimizes major incidents. Microsoft’s controlled feature‑flag model lets the company gather telemetry and feedback before widely enabling new Copilot integrations, which should reduce large‑scale regressions.

Risks and trade‑offs

• Licensing and vendor lock‑in. Requiring Microsoft 365 and a native Excel client to complete the convert flow ties a UX benefit to a subscription model. Organizations should weigh productivity gains against licensing cost and tenant governance.
• Detection accuracy and false expectations. The feature is early preview; complex tables will not always convert cleanly. Over‑reliance on early preview results may create additional cleanup work rather than saving time if detection misparses data.
• Hardware fragmentation. Gating to Copilot+ devices initially (beginning with Snapdragon) fragments the experience across device classes and could complicate internal pilots where fleets include mixed hardware. Verify intended Copilot+ behavior against hardware capabilities before broad rollouts.
• Stability concerns. Beta channel builds remain pre‑release software; known issues like install rollbacks, audio driver anomalies, and Xbox controller bugchecks underscore the risk of using these builds on production machines. Back up, test in pilots, and avoid deployment on critical endpoints.

Recommendations

• For enthusiasts: enable the Beta Channel on a spare device, toggle “get the latest updates,” and try the new Click to Do actions while reporting detection edge cases through Feedback Hub.
• For IT administrators: run a small, controlled pilot; validate licensing, hardware compatibility, and critical peripherals; and hold off on broad deployment until Copilot+ hardware guidance and driver stability are confirmed for your environment.

Conclusion​

Build 26120.5770 (KB5064089) for the Beta Channel is a polish‑first update that nudges Windows 11 further into a Microsoft 365‑integrated, Copilot‑assisted productivity paradigm. The Convert to table with Excel action and Live Persona cards demonstrate the direction Windows is taking: reduce context switches and let the shell act as a direct bridge to cloud services. The Narrator Braille viewer shows that accessibility remains part of that roadmap. However, the practical utility of these additions will vary by hardware, tenant licensing, and regional policy — and the Beta Channel nature of the build means Insiders should expect iteration, imperfect detection, and occasional regressions as Microsoft refines these experiences.
Expect Microsoft to expand Copilot+ support to more platforms, refine table detection accuracy in subsequent flights, and gradually open regional availability as compliance and telemetry questions are resolved. For now, the update is a meaningful step toward tighter integration between Windows, Copilot, and Microsoft 365 — but it’s one best experienced in a test environment that tolerates change.
