Microsoft has recently launched Windows 11 build 22635.3139 for Insiders on the Beta Channel. This update includes small bug fixes for testers who have enabled the Windows update toggle to receive the latest fixes as soon as they are available.

The release notes for build 22635.3139 mention a “handful of fixes to improve overall reliability”. Additionally, Microsoft has fixed a bug in Desktop Windows Manager (dwm.exe) that was impacting some Insiders in the previous Beta build 22635.3130. The team has also resolved an issue impacting Task Manager reliability in recent builds.

Last week, the Beta Channel received a larger update, including suggestions in Snap Layouts and a new settings experience for the Widgets board. Microsoft also added an option to unenroll a device from the Beta Channel and install the production version of Windows 11 version 23H2 without losing any personal data.

This is the first new Windows 11 Insider flight of the week, and the team may release builds for other channels tomorrow. Last week, the most significant changes came to the Canary channel with the expansion of the previously Surface-exclusive Voice Clarity AI feature, as well as a new Copilot shortcut at the right side of the system tray area of the taskbar.
