Windows 11 Build 22499 Dev Channel Insider Preview

Just last week Microsoft released the Preview Build 22494 to the Insider Dev channel which added a mute button directly to the Taskbar so users can stop embarrassing themselves over active calls, unaware that their mic is unmuted.

Now, Microsoft has released the Preview Update Build 22499 to the Dev channel which takes the Taskbar enhancements a step further. Although this release brings a plethora of fixes and improvements to the Windows 11 operating system, Microsoft’s focus has been on the application sharing feature which has been added to the Taskbar. We shall explore exactly what the hype is all about in the section below.

Moreover, Microsoft has also released an ISO version for Windows 11 Build 22499 which you can download (using the given guide below) and perform a clean install.

Let us now dig into what the Preview Build 22499 brings to the OS, and whether it is worth updating your system just yet.

Windows 11 Insider Preview Build 22499 Changelog

Share Open App Directly from Taskbar

This feature is the prodigy of this flight. Microsoft has added the ability to share your open applications directly through a button labeled Share this window which will be visible below the floating image when you hover over an app in the Taskbar. A user will no longer have to switch back and forth between applications to share their screens.

Right now, the only option given will be to share the screen through Microsoft Teams. However, Microsoft intends to expand this feature and is welcoming other apps to incorporate it as well.

Other communications applications can also add this capability to their applications.


When you are done sharing an app, you can then hover over the app in the Taskbar and click Stop sharing before you move on to the next app to share it too.

The ability to share applications is only being provided to live calls, and this feature is currently only being rolled out to selected users subscribed to the Dev channel. That said, the feature will gradually make its way to all users on the channel.

Sign into Clock App with Work or School Account

Users can now log into the Clock app using their work or school accounts. This then enables them to sync their schedules and meetings and never miss another important event. That said, Microsoft says that you need version 11.2110.32.0 or higher of the Clock app to be able to log in to either of those account types.

You can check your currently installed version by opening the app and then clicking on the Settings button. There, you can see the installed version in the top-right corner of the app.

If the app version is not what has been suggested by Microsoft, you can update it through Microsoft Store, click Library, and then click Get Updates.

All applications with a pending update will then begin installing updates. You can then recheck the updated version of the Clock app through the Settings page within the app, as mentioned above.

Known issues

Before updating to build 22499, we suggest that you read this section thoroughly as it highlights the problems with this flight that may cause trouble later:

  • [General]
    • Users updating from Builds or earlier, to newer Dev Channel builds using the latest Dev Channel ISO image, may receive the following warning message: “The build you are trying to install is Flight Signed. To continue installing, enable flight signing”. If you receive this message, press the Enable button, reboot the PC, and retry the update.
    • There are reports that some PCs are unable to install new builds, or other updates and the users may see an error code 0x80070002. If you are experiencing this issue, Microsoft suggests to reboot the PC and try again.
    • Some PCs may rollback with error code 0xc1900101-0x4001c when installing this build. Microsoft suggests that you pause the Windows updates for a while until they fix the issue.
  • [Start]
    • You might be unable to enter text when using Search from the Start Menu or the Taskbar. If you experience the issue, press the Windows Key + R shortcut keys to launch the Run dialog box and then close it. This may temporarily resolve the issue.
  • [Taskbar]
    • The Taskbar may flicker at times when switching input methods.
    • The clock in the Taskbar can get stuck and not update, mostly when accessing the PC via Remote Desktop.
  • [Windowing]
    • The displayed thumbnails and the content area may unexpectedly shrink while hovering the mouse back and forth between different desktops in Task View.
  • [Input]
    • Some users are experiencing an unexpected behavior of the keyboard lights (like Caps Lock) after updating to build 22494.
  • [Search]
  • [Quick Settings]
    • The volume and brightness sliders aren’t displaying properly in Quick Settings.

Some of the known issues have been experienced in previous flights before, and have continued to the recent ones as well. While some have been fixed by Microsoft and no longer exist. That said, there seem to be new issues in build 22499 when compared to the older flights.
