Windows 11 Insider build 22499 adds new way to share app windows to a Teams call

| |

Microsoft has just released the Windows 11 preview build 22499 for Insiders in the Dev channel, and the main new feature is the ability to quickly share open app windows to a Microsoft Teams call. When hovering over open windows on the taskbar, Windows Insiders will now see a “Share this window” button at the bottom of the pop up to share the content from an open app to Teams meeting calls.

"When you are in a meeting call through Microsoft Teams, simply hover over the apps running on your taskbar and you will see a new button that allows you to share your window with your meeting attendees. When you are done sharing your content, hover over the window again and click Stop Sharing or choose another window and click Share this Window. If you’re presenting a full screen presentation in PowerPoint, simply move your mouse to the bottom and your taskbar will pop up for you to share or stop sharing the presentation without interruption to your attendees,” the Windows Insider team explained.

By hovering over open windows on your taskbar, you can quickly share that window with a microsoft teams call.

This new sharing experience will only roll out to a subset of Windows Insiders who have installed the Microsoft Teams app for work or school accounts (which is separate from the built-in Teams app for consumers on Windows 11). The Windows Insider team said today that other communications apps will also be able to support this new sharing feature from the Windows 11 taskbar, and it will be interesting to see if Zoom, Discord, or other apps could soon take advantage of it.

Today’s build 22499 also brings various bug fixes and improvements for Clipboard history, File Explorer, and the Settings app. Starting with this build, keyboard focus visuals in Task View and Alt + Tab are also easier to see.

You can find the full list of fixes and known issues in the Windows 11 build 22499 below:

Fixes

[Input]

  • Clipboard history should be back up and running properly once you’re on this build.
  • Clicking gifs in the emoji panel will now actually insert them into supporting apps, unlike in the previous build.
  • Updated the backend dictionaries for several languages – the touch keyboard’s text suggestions and autocorrect should be more accurate now.
  • If you change your accent color the accents in the emoji panel should follow suit now, instead of getting stuck with the old color.
  • Fixed an IME crash that was happening sometimes for people who had chosen to use the previous version of the Pinyin IME.
  • Mitigated an explorer.exe crash that was happening sometimes recently related to touch keyboard usage.

[Windowing]

  • Made another fix to address an issue where explorer.exe would crash if you pressed ALT + F4 while ALT + Tab was open.

[Settings]

  • Fixed a Settings crash that could happen when trying to check remote sound properties while accessing a PC over Remote Desktop..

[Other]

  • Fixed an issue that was causing some clipping / unexpected zoom when going through OOBE on some ultrawide monitors.
  • The apostrophe in the error message when your fingerprint isn’t recognized on the login screen should display correctly now.
  • When taking a screenshot of a UWP app by pressing the New button in Snipping Tool, Snipping Tool should come into the foreground once the snip is done.
  • Fixed an issue that was causing some Insider PCs to bugcheck when coming out of sleep recently, with an error message saying “SYSTEM_THREAD_EXCEPTION_NOT_HANDLED”.
  • Fixed a deadlock that could happen related to MediaPlaybackCommandManager, resulting in certain apps not being able to play media sometimes.
  • Addressed an issue that was causing reports in Reliability Monitor to unexpectedly be blank with just an empty rectangle when going to see more info.
  • Did some work to help address an issue resulting in certain games having some lag that was only noticeable when the window was in focus. As a reminder if needed, please refer to the following documentation for filing actionable game perf feedback.

NOTE: Some fixes noted here in Insider Preview builds from the active development branch may make their way into the servicing updates for the released version of Windows 11 that became generally available on October 5th.

Known issues

[General]

  • Users updating from Builds 22000.xxx, or earlier, to newer Dev Channel builds using the latest Dev Channel ISO, 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.
  • We’re investigating an issue where some PCs are unable to install new builds, or other updates. The PC may report an error code 0x80070002. If you are experiencing this issue, please reboot your PC and try again.
  • Some devices may bugcheck with error code 0xc1900101-0x4001c when installing this build. If you hit this, after the device rolls back to the previous build, you may want to pause updates until we release a fix.

[Start]

  • In some cases, you might be unable to enter text when using Search from Start or the Taskbar. If you experience the issue, press WIN + R on the keyboard to launch the Run dialog box, then close it.

[Taskbar]

  • The Taskbar will sometimes flicker when switching input methods.
  • We’re investigating an issue in this build where the clock in the Taskbar can get stuck and not updated, particularly when accessing the PC via Remote Desktop.

[Windowing]

  • Hovering your mouse back and forth between different desktops in Task View will result in the displayed thumbnails and content area unexpectedly shrinking.

[Input]

  • We’re working on a fix to address reports from some Insiders that the lights on their keyboards, for example for caps lock, are not working properly after upgrading to the previous build.

[Search]

  • After clicking the Search icon on the Taskbar, the Search panel may not open. If this occurs, restart the “Windows Explorer” process, and open the search panel again.

[Quick Settings]

  • We’re investigating reports from Insiders that the volume and brightness sliders aren’t displaying properly in Quick Settings.

If you want to do a clean install, Microsoft has also made the ISOs for the Windows 11 build 22499 available to download on this page. Let us know in the comments if you think the ability to quickly share open app windows directly from your taskbar to a Microsoft Teams call is a welcome addition.
