Windows 11 Insider build 22494 adds new Mute call button to taskbar

Microsoft has just released the preview version of Windows 11 22494 for Insiders in the Dev channel, which introduces the ability to mute or unmute your microphone from the taskbar during Microsoft Teams calls. A new microphone icon will appear in the taskbar during a Teams call, allowing users to quickly mute and unmute their microphone.

This new experience is only rolling out to a subset of Insiders using Microsoft Teams with a work or school account, with support for Teams calling for consumers to come later. Microsoft will also allow other communications apps to use this new capability, and the microphone button will also be able to show the audio status of your call and which app is accessing your microphone.

Activate and deactivate the sound of your calls with the microphone icon in the taskbar.

Starting with this release, Microsoft is also experimenting with the appearance of snapshot groups in ALT + TAB and the task view. This new experience will only appear to some insiders, and Microsoft will listen to feedback before expanding it to more testers.

Today’s version 22494 also brings various fixes and improvements for Windows 11 taskbar, File Explorer, Settings app, and Windows Search. You can see the full list of changes, bug fixes, and known issues in version 22494 below:

Changes and Improvements

  • We’re trying to show snapshot groups in ALT + TAB and task view with some Windows Insiders, just like when you hover over open apps in the taskbar and see them there. It’s not yet available to all Insiders as we plan to monitor the comments and see how they land before we release it to everyone.
  • If you are looking for a file type or link types under Settings> Apps> Default apps, we will now display a drop-down list of options containing your current query without having to press Enter first.
  • If needed, you can now launch the installed apps settings page under Settings> Apps> Installed apps directly through this URI: ms-settings: installed-apps.
  • Adjustment of the names of the sort by options under Settings> Apps> Installed apps to make them clearer and added a new option to sort from smallest to largest.



  • Tooltips should no longer appear in random places on the taskbar after hovering your mouse over volume, battery, network, or other icons in the corner of the taskbar.
  • Addressed an underlying issue that caused some icons to unexpectedly duplicate in the corner of the taskbar.

[File Explorer]

  • Fixed an issue that caused the context menu to crash for some people if you tried to scroll it.
  • Did some work to help resolve an issue where in some areas of the screen context menu submenus were showing above the context menu rather than next to it (e.g. if you hovered over New) .
  • Context menu icons should now be less blurry on systems with multiple monitors with mixed DPI.
  • Addresses an issue that could cause selecting Open With from the shortcut menu to unexpectedly open the file in some cases rather than actually opening the Open With dialog box.
  • File renaming on the desktop is operational again in this flight.
  • Made another adjustment to the underlying command bar logic to help improve the performance of command actions in File Explorer.


  • Fixed a recent issue that caused the indexer database to be too fragmented, causing the indexer to unexpectedly consume a large amount of memory and CPU for an extended period of time. This was especially noticeable for people who have large Outlook mailboxes.


  • Addressed an issue that caused some apps to crash when trying to drag something with the Shift or Ctrl key held down.
  • Fixed an issue that prevented the touchscreen keyboard from appearing on tablets when you tap the text field if you try to reset your PIN from the login screen.
  • Improved reliability of the Pen menu.


  • Fixed some explorer.exe crashes related to the use of windowing features (snap, ALT + Tab and desktops).
  • If you open the task view on a system with multiple monitors, the background should now be acrylic on both monitors.
  • Addressed some UI issues with window thumbnails in Task View and ALT + Tab, including the fact that the close button might be muted if the application window was too thin.


  • Addressed an issue where Facial Recognition (Windows Hello) could be unexpectedly grayed out in login settings in some cases until you close and open settings.
  • Fixed an issue where Storage Sense would not clean up C: Windows SystemTemp.
  • Standard users (i.e. non-admins) should now be able to change the time zone in settings if location access is not granted, rather than the drop-down list going blank.


  • Fixed an issue causing links to Windows Update, Recovery and For developers to be displayed under the main Windows update settings page.
  • Fixed a bug where images had a yellow tone in Adobe Photoshop, Adobe Lightroom, and Adobe Lightroom Classic in HDR mode.
  • Mitigated an issue with DHCP that caused unexpected power consumption while the screen was turned off in recent versions of some Insiders.
  • Did some work to help resolve an issue where Service Host: WinHTTP Web Proxy Auto-Discovery Service was unexpectedly using a lot of CPU.
  • Fixed an issue that could cause a black screen to appear on some devices when they woke up from sleep mode (where the lock screen was not showing).
  • Addressed an underlying issue that caused some ARM64 PC users to experience an increase in Microsoft Teams crashes in the latest versions of Dev Channel.
  • We have increased the padding of the selected items as shown by clicking on Show more options in the context menu of the file explorer or on the menu options in the task manager.
  • WSL: fixed error 0x8007010b when accessing Linux distributions via `\ wsl.localhost` or` \ wsl $ `(problem # 6995).

NOTE: Some fixes noted here in the Insider Preview builds of the active development branch may be found in the maintenance updates for the released version of Windows 11 which became generally available on October 5.

Known issues


  • Users who update from versions or earlier to newer versions of the development channel using the latest ISO in the development channel may receive the following warning message: The version you are trying to install is Flight Signed. To continue the installation, activate the flight signature. If you receive this message, press the Activate button, restart the PC and try the update again.
  • Some users may see their screen and sleep times reduced. We are investigating the potential impact that shorter screen and sleep times could have on power consumption.


  • In some cases, you may not be able to enter text when using search from top or taskbar. If you have the problem, press WIN + R on the keyboard to launch the Run dialog box and then close it.


  • The taskbar will sometimes blink when changing the input method.
  • We are investigating an issue in this release where the taskbar clock may get stuck and not updating, especially when accessing the PC through the remote desktop.


  • Clipboard history indicates that it is empty even though it is enabled and must contain content. This is a UI issue that we are investigating: When a flight runs with a patch, all pinned items should become available again.


  • After clicking the Search icon on the taskbar, the Search panel may not open. If this happens, restart the “Windows Explorer” process and reopen the search panel.

[Quick Settings]

  • We are investigating reports from Insiders that the volume and brightness sliders do not display correctly in Quick Settings.

While Microsoft continues to test new features with a subset of Windows Insiders on the Development Channel, the new Windows Subsystem for Android and integration with the Amazon Android App Store remains only available on the Beta Channel. The Windows Insider team previously said that Dev Channel will end up testing Android apps, but there is still no ETA.
