Microsoft brings the Build 22494 version update to Win11 Dev preview users

Microsoft pushed the Build 22494 version update to Win11 Dev preview users, bringing the taskbar one-click mute microphone, and contains multiple repair functions.


The microphone can be muted with one key in the taskbar. Starting with Microsoft Teams, users will find that the microphone icon is automatically added to the taskbar during a call. The user can view the audio status of the call, the application that is accessing the microphone, and quickly mute and unmute the microphone at any time.

When a user joins a meeting, the user will immediately see the following icon in the taskbar. The icon will appear throughout the call, so it can be obtained at any time no matter how many windows are open on the screen.

Moreover, this feature was first promoted to the Windows Insiders user groups of Microsoft Teams for Work or Schools, so not everyone was able to use this feature at the beginning.


  • Some Windows Insider members display snap groups in Alt + Tab and Task View, just like the application opened by the user hovering the mouse on the taskbar. Not all insiders can use this feature. Microsoft plans to monitor the feedback and check the feedback, and then push it to all users.

  • Searching for the file type or link type under “Settings”> “Applications”> “Default Applications” will display a drop-down list of options containing the user’s current query without pressing the Enter key.

  • Users can directly launch the installed application settings page under “Settings”> “Applications”> “Installed Apps” through the following URI: ms-settings:installed-apps.

  • Adjusted the name of the sorting method under “Settings”> “Apps”> “Installed Apps” to make it clearer, and added the option of sorting from small to large.
