Microsoft’s relentless drive to refine Windows 11 has reached a new milestone with the release of two preview builds—26200.5710 (KB5062676)—to both the Dev and Beta Channels of the Windows Insider Program. The simultaneous release of these builds underscores Microsoft’s intention to blur the historic lines between “experimental” and “stable” channels, giving power users and early adopters the same taste of cutting-edge innovations and bugfixes. This update is far more than routine maintenance; it ushers in several noteworthy advancements, including novel accessibility features powered by on-device AI, a transparent slowdown logging system designed to root out performance stutters, and a variety of important tweaks that signal the company’s ongoing commitment to user-centric design. As with any substantial update, alongside new strengths and fresh utility come new quirks and issues—some of them more consequential than others. What follows is an in-depth look at the contents of these builds, how the new features work, and what they mean for the Windows ecosystem going forward.
At the center of this update’s feature set lies a clear focus: accessibility powered by artificial intelligence and delivered via Copilot+ PCs—devices built on the latest Intel and AMD silicon optimized for AI tasks. Microsoft is touting new capabilities that specifically enhance the experience for users with visual impairments, while at the same time offering valuable productivity tools for the broader user base.
Importantly, because processing happens locally, sensitive data never leaves the device, preserving user privacy while reducing dependence on persistent internet connectivity. In practice, this feature is poised to benefit not just individuals with disabilities but also professionals who need alt text and instant summaries in their workflows—a twofold boon for digital accessibility and general productivity.
A key improvement here is interactivity: users can regenerate descriptions, express satisfaction by liking or disliking, and easily copy the generated results for use elsewhere. By empowering users to fine-tune and iterate, Microsoft is signalling a shift from static, one-way accessibility to a more dynamic assistive platform. It is worth noting that while the quality of these narrations has improved, the underlying AI’s error rate and context sensitivity in describing ambiguous or highly detailed images remains to be evaluated independently in practice. The benefit, however, is already palpable: richer digital experiences and a tangible decrease in the friction that often accompanies accessing non-textual information.
In real terms, this could help resolve a long-standing problem where users encounter sluggish behavior that then vanishes before they can report it or have it diagnosed. The automatic nature of the log capture ensures debugging information exists as soon as the issue occurs, rather than relying on after-the-fact recall or incomplete self-reporting.
Giving users the ability to monitor and control app permissions for local AI models not only enhances security but also aligns with growing public demand for greater autonomy and privacy. Notably, while the user interface for this feature is now present, full functionality is promised for a forthcoming update. This staged rollout, typical for Insider builds, means early adopters may encounter a disconnect between what’s visible in the UI and what’s actionable—a minor but noteworthy caveat.
Nevertheless, with innovation comes the need for caution: the heavy reliance on Copilot+ hardware, ongoing regressions and compatibility issues, and the early, sometimes incomplete state of key features mean that broad adoption is not yet advisable for everyone. For enterprises, accessibility advocates, and the legions of power users who thrive on the bleeding edge, these builds are worth close attention. The stage is set for a major shift in how users experience and contribute to the evolution of Windows—one marked by more power, but also by a greater stake in shaping its contours through feedback and insight. As always, the Windows journey is both an evolution and a communal project, and these preview builds mark another crucial step forward on that path.

The Era of Copilot+ PCs: AI Accessibility on the Desktop
At the center of this update’s feature set lies a clear focus: accessibility powered by artificial intelligence and delivered via Copilot+ PCs—devices built on the latest Intel and AMD silicon optimized for AI tasks. Microsoft is touting new capabilities that specifically enhance the experience for users with visual impairments, while at the same time offering valuable productivity tools for the broader user base.On-Device AI Image Descriptions in Click to Do
For years, automatic image captioning was the province of cloud-based services, with concerns around privacy, speed, and accuracy. Microsoft’s newly announced feature sidesteps these bottlenecks by leveraging on-device AI processing for its Click to Do preview application. Users with Copilot+ PCs can now receive autogenerated descriptions of images—enabling a “quick overview of the visual content.” For those who rely on screen readers or need accessible documentation, this means faster access to information, improved alt text for web and document images, and on-the-fly summaries of complex charts or photographs.Importantly, because processing happens locally, sensitive data never leaves the device, preserving user privacy while reducing dependence on persistent internet connectivity. In practice, this feature is poised to benefit not just individuals with disabilities but also professionals who need alt text and instant summaries in their workflows—a twofold boon for digital accessibility and general productivity.
Enhanced AI in Windows Narrator
Narrator, Windows’ built-in screen reader, now inherits these image description powers through integration with Copilot+ AI. The AI can provide detailed, contextually rich captions, as illustrated in Microsoft’s own documentation: “The image is a graph showing the stock prices of Microsoft Corporation, with the S&P 500 and NASDAQ Computer indexes. The graph shows a steady increase in Microsoft’s stock price over the period from June 18th to June 23rd.”A key improvement here is interactivity: users can regenerate descriptions, express satisfaction by liking or disliking, and easily copy the generated results for use elsewhere. By empowering users to fine-tune and iterate, Microsoft is signalling a shift from static, one-way accessibility to a more dynamic assistive platform. It is worth noting that while the quality of these narrations has improved, the underlying AI’s error rate and context sensitivity in describing ambiguous or highly detailed images remains to be evaluated independently in practice. The benefit, however, is already palpable: richer digital experiences and a tangible decrease in the friction that often accompanies accessing non-textual information.
Logging and Diagnosing Slowdowns: A New Layer of Transparency
Perhaps the second-most significant addition in these preview builds is the introduction of a “slowdown logging system.” This feature targets one of Windows’ perennial headaches: unexplained sluggishness. Instead of leaving users frustrated or IT departments guessing, performance dips are now automatically logged. When a user experiences lag and files feedback via the Feedback Hub (specifically in the “System Sluggishness” category), these logs are sent automatically to Microsoft’s engineering teams.How Slowdown Logging Works
The system is architected for both transparency and privacy. All logs are stored locally by default at%systemRoot%\Temp\DiagOutputDir\Whesvc, and are only sent to Microsoft if and when the user initiates feedback through the Feedback Hub. This approach gives users full control over their diagnostic data, alleviating reasonable privacy concerns that often accompany telemetry and diagnostics in tech ecosystems. This targeted data submission aids Microsoft’s engineers in pinpointing recurring issues and, presumably, rolling out quicker fixes and performance improvements.In real terms, this could help resolve a long-standing problem where users encounter sluggish behavior that then vanishes before they can report it or have it diagnosed. The automatic nature of the log capture ensures debugging information exists as soon as the issue occurs, rather than relying on after-the-fact recall or incomplete self-reporting.
Expanded Controls and System Visibility
Besides accessibility and diagnostics, these preview builds include a set of smaller but strategically important features and tweaks. Chief among them is increased transparency and control over AI-powered functionalities.Generative AI Usage Dashboard
Within the new builds, users can explore a dedicated area in Settings (Settings > Privacy & Security > Text and Image Generation) where they can see which third-party applications have recently accessed generative AI models provided by Windows. This feature addresses one of the most common modern computing anxieties: the lack of clarity around which applications use advanced AI capabilities, and when.Giving users the ability to monitor and control app permissions for local AI models not only enhances security but also aligns with growing public demand for greater autonomy and privacy. Notably, while the user interface for this feature is now present, full functionality is promised for a forthcoming update. This staged rollout, typical for Insider builds, means early adopters may encounter a disconnect between what’s visible in the UI and what’s actionable—a minor but noteworthy caveat.
Quality of Life Improvements and UI Refinements
In addition to the major highlights, the latest preview builds offer a steady trickle of user experience enhancements—both under the hood and in daily interaction points.Click to Do Tweaks
For users on Copilot+ PCs, the Click to Do preview app sees iterative refinement, including the removal of the search box from the top bar, potentially streamlining the interface but also sparking debate about balancing simplification with user capability. The response from Insiders will likely guide whether this change makes it into general release.Lock Screen Widget Discoveries
The lock screen widget experience is evolving as well. Windows Insiders in the Dev Channel now see widget suggestions, making it easier to find and enable useful lock screen enhancements. Microsoft notes that this experience is still experimental and subject to “change in future flights,” suggesting an A/B testing approach and ongoing focus on refining user onboarding and discoverability.Notification Center and Bug Fixes
Several fixes are gradually rolling out, such as an improved Notification Center that now displays content correctly when the clock is enabled, and a key stability fix that addresses explorer.exe and other app crashes linked todbgcore.dll. Each of these adjustments speaks to ongoing stability and usability improvements, though the gradual nature of the rollout means not all users will see these benefits immediately.Known Issues: What’s Broken and What’s Next
No Insider build is complete without a few caveats, and this release is no exception. Microsoft’s transparency in listing open bugs is refreshing, though the list itself underscores both the complexity of Windows and the realities of moving fast with experimental features.Notable Known Issues
- Update Failures: Some users may experience a rollback with error code
0x80070005during install. A workaround is available viaSettings > System > Recovery > “Fix issues using Windows update”. - Start Menu Quirks: Touch navigation is unreliable in the latest “new Start menu” (notably, the swipe-up gesture is unsupported, and drag-and-drop from “All” to “Pinned” is limited).
- Live Captions Instability: Attempting to use live translation in Live Captions on a Copilot+ PC may result in crashes.
- Xbox Controller Bluetooth Bug: Some users report that connecting an Xbox controller via Bluetooth causes a system bugcheck. The fix involves manually uninstalling the problematic driver (
