Microsoft has begun rolling out a targeted update to the Copilot app on Windows that brings semantic file search to Copilot+ PCs and introduces a redesigned Copilot homepage for Windows Insiders, marking a clear step toward tighter on‑device AI integration in Windows. rr channel updates over the summer have steadily introduced Copilot‑related features tied to the company’s Copilot+ PC initiative. These features are being enabled gradually and are frequently gated by device capabilities, markets, and Insider rings. The current wave described by Microsoft and community trackers bundles semantic search, enhancements to Click‑to‑Do, Recall improvements, and UI updates across File Explorer and Settings.
The rollout is not universal: Microsoft eCopilot+ features, meaning eligible users—Insiders on supported Copilot+ hardware—will see functionality appear over days or weeks rather than immediately after installing a build. That staged pattern is again in effect for the semantic search and homepage changes.
Key points:
Microsoft’s Copilot on Windows effort is shaping into a coherent platform play: a mix of local AI acceleration, OS‑level integra capabilities behind licensing gates. For Insiders, the preview provides an early look at how natural‑language search and on‑device AI can change daily workflows. For businesses, the release is a remive of endpoint innovation will require coordinated planning across hardware procurement, policy controls, and identity/licensing models. The rollout’s staged nature gives administrators breathing room to pilot features and build governance, but organizations shouly—what’s opt‑in today may be an enterprise configuration decision tomorrow.

The rollout is not universal: Microsoft eCopilot+ features, meaning eligible users—Insiders on supported Copilot+ hardware—will see functionality appear over days or weeks rather than immediately after installing a build. That staged pattern is again in effect for the semantic search and homepage changes.
What’s new in this update
Semantic file search: what it does
- **Semas the system interpret natural language descriptions and return files, images, or settings that match intent and context rather than only literal filename or keyword matches.
- It integrates semantic indexing alongside traditional indexing so queries like “photos of the bridge at sunset” or “the final budget for our Europe trip” aim to surface relevant results even when filenames don’t contain those exact words.
Where it runs: Copilot+ PCs and on‑device AI
- The feature is currently available only on **Copilotffied for on‑device AI acceleration. Initial availability favors Snapdragon‑powered models, with Intel and AMD devices receiving phased support later.
- Microsoft emphasizes on‑device processing for privacy and responsiveness. The semantic indexing and inference work are intended to run locally oP—so results can be delivered without a round trip to the cloud. Several community writeups and Insider summaries reference NPUs with multi‑TOPS performance claims as the enabling hardware.
New Copilot homepage and UI changes
- The Copilot home experience (the app’s homepage and quick‑view surfaces) received a redesign to highlight recent snapshots, top apps, and frequentlytng recall and contextual suggestions easier to access.
- Click‑to‑Do gains a new first‑run interactive tutorial and additional actions like a Refine option that performs on‑device text improvements. File Explorer context menus now surface Copilot‑powered actions such as Visual Search, BlObjects, and Summarize (the latter may require a Microsoft 365 Copilot license).
How semantic search works (high‑level technical overview)
Semantic indexing + traditional indexing
Semantic search adds a layer of understanding on top of the Windows indexer. Instead of only matching strings, it creates semantic relationshe (including OCRed image text and document text). The Windows index remains in play for basic lookups, but the semantic layer attempts to infer intent and rank results by relevance.Key points:
- Index scope is user‑configurable through Searching Windows settings; an “Enhanced” indexing mode expands coverage to more locations.
- Supported local file formats currently include common document and image formats (PDF, DOCX, XLSX, JPG, PNG, etc.), though exact format coverage varies with ongoing updates.
On‑device inference and NPUs
Microsoft’s design routes semantic model execution to on‑device accelerators (NPUs) on C provides:- Faster response times and lower latency for conversational or descriptive queries.
- Improved privacy posture because queries and indexing metadata can remain local than being sent to cloud services for interpretation.
Availability, licensing, and prerequisites
Who gets it first
- Windows Insiders on Copilot+ certified devices (initially Snapdragon models).
- Feature expansions to AMD and Intel Copilot+ devices are planned but rolled out later.
- Some Copilot actions in File Explorer (e.g., Summarize) require Microsoft 365 Copilot licenss and software requirements
- Latest Copilot app versions (distributed via Microsoft Store), with reported Copilot version identifiers beginning at 1.24112.123.0 in recent insider releases.
- Windows Insider builds containing the platform bits (for example, certain Canary/Dev/Release Preview builds noted by Microsoft), plus hardware that meets Copilot+ certification.
rosoft uses gradual enablement (A/B style gating) to control exposure to Copilot+ experiences. That means receiving the build does not guarantee immediate feature visibility; staged flags and telemetry determine who sees what and when. Administrators and users should expect staggered availability.
Strengths and practical benefits
- Productivity: Semantic search srcan’t remember filenames or folder locations. Searching by intent or description shortens the path to the right file or setting, streamlining daily workflows.
- On‑device privacy: Running models locally on Copilot+ hardware addresses a core privacy concern—sensitive queries don’t need to leave the device for interpretation is attractive for both privacy‑conscious consumers and regulated enterprise environments.
- Accessibility and discoverability: The redesign of Copilot’s homepage and the interactive Click‑to‑Do tutorial improve discoverability for new users, while expanded Live Captions with style Settings integration broaden accessibility.
- Tighter OS integration: Surface‑level AI actions in File Explorer and Settings demonstrate Microsoft’s intent to bake generative and contextual AI into the operating system rather than leaving it as standalone cloud services. ws as a contextual productivity layer.
Risks, caveats, and unresolved questions
Privacy and data governance
- Even with local encryption and TPM/Windows Hello protections touted for Recall and local snapshotting, storing richer indexed snapshots aeases the device’s attack surface. Enterprises will need to evaluate retention policies, encryption keys, and remote wipe strategies when deploying Copilot+ devices. Microsoft frames Recall as opt‑in and locally encrypted, but the practical governance model for managed fleets is still maturand enterprise controls
- Corporate environments will demand robust administrative controls and audit trails before enabling snapshotting or semantic indexes across managed devices. The current preview emphasizes opt‑in defaults; however, IT teams will want explicit group policy or MDM controls and clear guidance for Deprovisioning. Community reporting notes these areas as active concerns.
Hardware gating and fragmentation
- The Copilot+ hardware requirement creates a bifurcated experience across the Windows ecosystem. Users on oertified devices will not receive the same semantic capabilities, which could create productivity gaps inside mixed fleets. The timeline for broad Intel/AMD support remains unspecified.
Accuracy, hallucinations, and dependence on indexing scope
- Semantic search quality depends on the breadth and freshness of what is indexed. If critical folders are excluded from indexing, queries won’t find those filrence could surface unexpected results or show false positives—particularly in early preview stages—so users should treat results as suggestions rather than absolute proof of content. Several preview notes underline that scope limitations (local only; cloud integration planned) may mislead users initially.
Unverified hardware claims
- While communUs and multi‑TOPS figures, any specific claims about NPU TOPS counts or precise performance numbers should be treated with caution until verified against OEM and silicon vendor specifications. These figures can vary by model and SKU. Flagged: verify with vendor specs before relying on precise TOPS numbers for procurement decisions.
Practical guidance for Insiders and IT pros
If you’re an Insider on a Copilot+ PC
- Confirm your device is Copilot+ certified and up to date with the latest Insider build and Microsoft Store Copilot ap recommended).
- Opt into enhanced indexing only after reviewing which folders will be included; consider excluding directories that contain highly sensitive data.
- Test semantic queries and Click‑to‑Do actions on non‑sensitive files first to get a feel for result quality and latency.
If you manage devices for an organization
- Evaluate Copilot+ features in a controlled pilot group before widell snapshot policies, local encryption keys, and the ability to centrally disable features via MDM.
- Require that features which integrate with Microsoft 365 Copilot have the appropriate licensing and data governance agreements in place when those caph corporate content.
- Track Microsoft’s administrative controls and privacy settings as the Insider previews progress—expect more enterprise‑orienteto appear as the product matures.
What to watch next
- Expansion from Snapdragon to Intel and AMD Copilot+ certifications and the timeline for that transition. Multiple preview reports indicate Intel/AMD support is planned but staged.
- Cloud integration with OneDrive: at present semantic search targets locally indexed files; future updates are expected to add cloud seard other Microsoft cloud services. Monitoring Microsoft’s rollout notes and Insider changelogs will be necessary to confirm timing.
- Administrative and MDM controls for Recall and semantic indexings—these are the gating items for broad corporate adoption.
- Any official verification of hardware performance claims (NPU TOPS counts) from SoC manufacturers and OEMs; until then, treat bench numbers mentioned in previews as indicative, not definitive.
Critical takeaways
- Microsoft’s move to add semantic file search to Windows via Copilot is a meaningful UX shift: searching bxact text has clear productivity gains for many users.
- The strategy of on‑device AI—processing semantic queries locally on Copilot+ hardware—addresses privacy and latency concerns and positions Windows differently from purely cloud‑centric approaches.
- The launch is intentionally consedware gating, gradual rollout, and licensing requirements* mean most users won’t see the full vision immediately. IT pros should plan pilots and govan at the point of mass deployment.
- Several claims and hardware performance metrics currently circulating in previews remain partially verified and should be checked against vendor documentatprocurement or security policy decisions. Treat preview numbers as provisional.
Microsoft’s Copilot on Windows effort is shaping into a coherent platform play: a mix of local AI acceleration, OS‑level integra capabilities behind licensing gates.
