Microsoft today released Windows 11 Build 26120.1912 (KB5043168) to Insiders in the Dev channel. It brings with it 6 GHz support for the Mobile Hotspot feature, along with the several fixes and general improvements. Here are the details.

Note: Some of the changes are only available to Insiders who have enabled the "Get the latest updates as soon as they're available" option in Settings > Windows update, similarly to the Beta channel

Changes and improvements

General

This update includes a small number of improvements and fixes designed to improve the overall experience of the operating system.

Mobile hotspot

Windows Mobile Hotspot (Access Point) has been upgraded to support 6 GHz connections. This band requires chips that support this feature and updated drivers. Not all chips that support 6 GHz Wi-Fi will be able to create a mobile hotspot in the 6 GHz band.

You can see the change in Settings > Network & Internet > Mobile Hotspot when editing the hotspot properties. To be compatible with existing devices, 6 GHz will only be used if the user has enabled it.

Fixes

Open Source Software

Added attributes to credits.txt files for Rust OSS components.

Task Manager

• Fixed an issue where the settings page could have a white background when it shouldn't.
• Fixed an issue where Task Manager would become unresponsive when switching from a high-contrast theme to a normal theme.

Input Method Editor (IME)

Fixed a memory leak that occurred when closing a window while keyboard focus was set to a drop-down list.

WebView2 apps

Fixed an issue where WebView2 applications would not recognize input from Xbox 360 and Bluetooth controllers.

Known issues

Start Menu: If you click or tap a letter in the All Apps list in the Start menu, the list will stop working correctly. To fix this, try restarting your computer or restarting the explorer.exe process.
