Windows 11 Insider Preview Build 26120.5790: Enhancements and Fixes

Microsoft has released Windows 11 Insider Preview Build 26120.5790 to Windows Insiders in the Beta Channel, introducing significant improvements for users with Copilot+ PCs. The update includes a range of features aimed at streamlining voice-based input, expanding camera capabilities, and addressing various issues affecting performance and usability.

Enhancements

1. Fluid Dictation in Voice Access: A new feature that leverages on-device small language models to automatically correct grammar, punctuation, and filler words in real-time. This feature is available in all English locales and works across most applications, excluding secure fields like passwords.
2. Expanded Camera Capabilities: Windows Studio Effects can now be utilized with a broader range of camera hardware, including USB webcams. To use this feature, users need to update their driver via the new setting within Bluetooth & devices > Cameras.

Changes and Improvements

1. New Agent in Settings Experience: Users with French as their primary display language will see a new agent in the Settings experience.
2. On-Hover Actions in File Explorer Home: This feature allows users to quickly manage files by offering options like "Open file location" and "Ask Copilot about this file" when interacting with files.
3. Temporary Reversion of "For Developers" Section: The "For Developers" section in Advanced Settings has temporarily reverted to its previous state.

Fixes

1. Addressing Performance Issues: Several fixes have been implemented to address underlying issues causing lag in File Explorer, taskbar interactions, and browser windows, particularly during video playback.
2. Resolved Issue with Misaligned App Preview Windows: An issue causing misaligned app preview windows in the taskbar after display resolution changes has been resolved.
3. Corrected Context Menu Behavior: The context menu behavior in File Explorer, which could previously switch between normal and "Show more options" views with each right-click, has been corrected.
4. Resolved Issue with Settings > System > Storage > Temporary Files: This section no longer gets stuck during file scanning.
5. Fixed Event Error Related to Microsoft Pluton Cryptographic Provider: An event error related to the "Microsoft Pluton Cryptographic Provider" not loading on boot has been fixed.

Known Issues

1. Investigation into PCs Experiencing Bugchecks During Hibernation: A bugcheck (green screen) issue during hibernation is being investigated, with a recommendation to avoid hibernation if this issue occurs.
2. Issue with Shared Section in File Explorer Home: The Shared section might display even if there is no content.
3. Developers' Issue with PIX on Windows: Developers may encounter an issue where PIX on Windows cannot play back GPU captures, with a new PIX release expected by the end of September to address this.
4. Audio Problems with ACPI Audio Compositor: Audio problems resulting in a yellow exclamation mark in Device Manager for devices like "ACPI Audio Compositor" are being addressed by providing instructions to update the driver.
5. Bugchecks When Using Xbox Controllers via Bluetooth: Some Insiders are experiencing bugchecks when using Xbox Controllers via Bluetooth, and uninstalling the "oemXXX.inf (XboxGameControllerDriver.inf)" driver from Device Manager may resolve this issue.

Overall, this update aims to improve performance, usability, and camera capabilities for users with Copilot+ PCs. However, Microsoft's development team is still addressing some known issues.
