  • Microsoft released Windows 11 Insider Preview Build 26120.4733 via the Beta Channel, focusing on new features like the “describe image” action in Click to Do and updates to privacy settings.

  • Bug fixes address issues with the taskbar, File Explorer performance, live captions, and more, while known problems like potential rollout errors and limited touch navigation remain under investigation.

Microsoft announced the release of Windows 11 Insider Preview Build 26120.4733 (KB5062651) to the Beta Channel for Windows 11, version 24H2, today. This update introduces new capabilities, adjustments, and repairs for advanced users participating in the Windows Insider Program.

A notable feature in this build is the “describe image” action in Click to Do, part of the Copilot+ PC ecosystem. This addition allows users to generate detailed text summaries of images, charts, and graphs directly from their devices. The action processes data locally, ensuring privacy by keeping sensitive information on the user’s system. The feature is initially available for Snapdragon-powered Copilot+ PCs, with planned support for AMD and Intel models in future updates. Beta users are encouraged to test the functionality and report any issues through the Feedback Hub.

The update also includes updates to security measures. Microsoft introduced administrator protection, a new platform security feature designed to limit continuous administrative privileges. This function requires users to enable it manually via Windows Security under Account protection or through group policy. Additionally, Smart App Control is gaining attention in the Dev and Beta Channels, as some users who previously tested related updates may see the feature activated in Windows Security. Insiders can toggle it off through the same settings.

Several user interface improvements are part of the rollout. Privacy dialog designs for app permissions now appear as system modal alerts, meaning they center automatically and dim the screen for better visibility. This applies to permissions like location, camera, and microphone access. Microsoft emphasized that this change helps users prioritize privacy decisions.

Bug fixes span multiple system areas. The taskbar saw resolutions to issues such as random File Explorer preview windows appearing when hovering over app icons and inconsistent search box animations. File Explorer updates address problems with progress dialogs, zip file extraction speed, and the display of thumbnails for updated shortcuts. Live captions received a fix for opacity settings not applying through the Accessibility menu. Dynamic Lighting and graphics stability improvements are highlighted, including cursor synchronization in full-screen games after using ALT + Tab.

Known issues persist in the build. Some users may face rollback problems when installing the update due to error 0x80070005, for which Microsoft is working on a solution. A new error in the Group Policy Editor about “unexpected elements” is also under investigation. The redesigned Start menu includes touch navigation and drag-and-drop limitations, while Xbox Controllers paired via Bluetooth risk causing system crashes. A temporary fix for this involves uninstalling the Xbox GameControllerDriver through Device Manager. Additionally, the Microsoft Changjie Input Method is nonfunctional, and users are advised to revert to previous settings until a fix is available.

Microsoft reiterated its approach to Controlled Feature Rollout for the Beta Channel, where select updates are distributed to smaller Insider groups before wider adoption. The company also reminded users that some experimental features may never reach mainstream Windows releases. The changelog provided in the original announcement, including details about enablement packages and localization challenges, remains relevant for Beta participants.

Implications of the update include refined AI integration for visual analysis, stronger security protocols, and smoother performance in core applications like File Explorer and gaming. Microsoft continues to prioritize feedback from the Insider community to address bugs and refine upcoming features. With ongoing Rollout trips to resolve accessibility and compatibility issues, the focus remains on balancing innovation with stability for testing environments.
