Microsoft announced today the availability of Windows 11 Insider Preview Build 26120.4741 (KB5062678) for participants in the Beta Channel using Windows 11, version 24H2. This update includes improvements, fixes, and new features, primarily focused on Accessibility and AI integration for Copilot+ PCs. The company emphasized that updates in the Beta Channel are delivered through an enablement package to preview enhancements in future Windows releases.
New Accessibility Features for Copilot+ PCs
A highlight of this build is the expansion of Accessibility tools for Copilot+ PCs, specifically AMD and Intel-powered devices. Microsoft added a "describe image" function to Click to Do, enabling users to generate detailed descriptions of images, charts, and graphs. This feature, previously available on Snapdragon devices, allows users to click an item and receive a local AI-generated summary—ensuring sensitive data remains on the device. It benefits scenarios such as analyzing visual data or creating alternative text for content.
Separately, Narrator, Microsoft’s screen-reading tool, now supports richer image descriptions via AI on Copilot+ PCs. Users can activate the feature by pressing Narrator key + Ctrl + D, prompting a generated summary of on-screen visuals, including people, objects, and text. For example, a stock performance graph might receive a description like, “The image is a graph showing Microsoft’s stock price increase from June 18th to 23rd.” Non-Copilot+ devices will continue to rely on basic image descriptions.
Performance and Privacy Enhancements
Microsoft is improving system performance by collecting logs when PCs experience slow or unresponsive behavior. These logs, stored locally under the %systemRoot%\Temp\DiagOutputDir\Whesvc folder, will be submitted to the company via Feedback Hub if users report issues. Additionally, users can now monitor AI model usage in Settings > Privacy & Security > Text and Image Generation, which lists third-party apps accessing AI tools built into Windows. Control options for these apps will arrive in a future update.
Known Issues and Fixes
Some users may face install errors due to a 0x80070005 code when applying the update, which could trigger a rollback. Microsoft recommends using Fix issues using Windows Update in Settings > System > Recovery for affected users. Bluetooth Xbox Controller users may experience system crashes, resolved by uninstalling the XboxGameControllerDriver via Device Manager.
Additional Updates and Tweaks
The Click to Do menu will remove its search bar in upcoming iterations. A "Discover Widgets" toggle in Settings > Personalization > Lock Screen allows users to enable or disable suggested widgets on the lock screen. The new Start menu has Known Limitations, including unreliable touch navigation and restricted drag-and-drop functionality. Another issue in Live Captions and the Changjie Input Method affects initial AI feature interactions, with fixes planned for later updates.
For Windows Insiders in the Beta Channel, new features like Widget Discovery and drag-and-drop improvements will expand gradually. Microsoft uses Controlled Feature Rollout to monitor user feedback before wider distribution. Enabling the "Get latest updates" toggle in Settings > Windows Update allows early access to these changes.
Features in the update are not guaranteed for final release, as the company tests evolving concepts with the Insider community. Some Accessibility tools may not yet work seamlessly with experimental features like Recall. Localized languages might also have missing translations, requiring further feedback.
Users can report issues via Feedback Hub (activated by WIN + F) under Accessibility > Narrator or Desktop Environment > Click to Do. For non-Copilot+ PCs, the Windows Update servicing process remains unchanged, with older methods for managing feature preview settings.
The company reiterated that Dev and Beta Channels operate as parallel development paths, with some features appearing in the Beta Channel ahead of the Dev Channel. Insiders are encouraged to use Flight Hub to track which builds are active in each channel and stay informed about upcoming changes.
Microsoft stated its ongoing commitment to Accessibility and AI advancements, ensuring these tools align with user needs while maintaining data privacy for Copilot+ PC users. Key features introduced today will evolve based on Insider feedback, with resolutions to known bugs planned for future updates. Those interested in testing new capabilities can monitor this channel for incremental changes as development progresses.
