Microsoft has released cumulative update KB5124036 (Build 26220.9202) for Windows 11 version 25H2, available to insiders on the Beta channel. The build includes fixes and improvements for File Explorer, Windows Recovery Environment, Search, Taskbar, Settings, and Input, as well as removes the WMIC utility and the "Drag Tray" feature. The main changes are listed below.
- File Explorer — Home page. The Home page in File Explorer launches faster and is more responsive to actions.
- File Explorer — Recommended section. The "Recommended" section on the "Home" page supports touch scrolling of the file carousel.
- File Explorer — preview fix. Fixed an issue introduced in the previous build that caused a wide bar to appear across the image in File Explorer preview.
- Windows Recovery — automatic Wi-Fi connection. Windows Recovery Environment (WinRE) now automatically uses appropriate Wi-Fi profiles already saved in the main system, including supported certificate-authenticated Wi-Fi networks. Previously, WinRE connected on its own only to unauthenticated wired Ethernet networks or to Wi-Fi networks separately configured for the recovery environment, and users had to manually enter passwords for other WPA2 and WPA3 networks. Now, when a recovery scenario requires a network connection, WinRE uses the saved Wi-Fi profile information. The device connects to the internet automatically — for example, when using the "Quick Machine Recovery" feature or reinstalling the system via Cloud Rebuild, without separate preparation of Wi-Fi credentials by the user or IT administrator. The feature is enabled by default, but an IT administrator can disable it.
- WMIC removal. The Windows Management Instrumentation Command-line (WMIC) utility has been removed from this release. The change is part of the gradual deprecation and removal of WMIC from Windows.
- Search. The height of the search box has been increased by 4 pixels.
- Removal of the "Drag Tray" feature. Based on feedback from Windows Insider Program participants, Microsoft has removed the "Drag Tray" feature from this build. The company continues to work on improvements in this area and promises to share details about a future replacement in one of the upcoming updates.
- Settings. Fixed an issue introduced in the previous build that caused Settings to crash when interacting with elements on the "Date & Time" page.
- Taskbar. Improved reliability of loading the taskbar notification area on PCs without a touchscreen.
- Input. Improved input reliability with the Japanese IME — freezes and deadlocks occur less frequently.
- Other. Fixed an xtajit64.dll crash that caused problems with certain applications on Arm64 PCs in recent builds.
To install the update, go to Settings > Windows Update and click Check for updates. A restart of the computer will be required to complete the installation.
