Personalization Enable or Disable Share any Window from Taskbar in Windows 11

This tutorial will show you how to enable or disable the ability to quickly share the content from open app windows directly from the taskbar for your account in Windows 11.

Starting with Windows 11 build 22499, Microsoft added the ability to quickly share the content from open app windows directly from your taskbar to your meeting calls. This experience, also starting with Microsoft Teams, eliminates the need to flip back and forth across applications just to share or reshare a window. There are no interruptions to your meeting attendees or what they see on screen – share any open window during your call.

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.

Other communications applications can also add this capability to their applications. The capability to share your meeting call applies only to your current meeting call.

Starting with Windows 11 build 26100.7309 (24H2) and build 26200.7309 (25H2), when you hover over an open app icon on the taskbar, a thumbnail preview of the app window appears with a new Share with Copilot button beneath this preview. Selecting it allows Copilot Vision to scan, analyze, and offer insights on the content displayed by the app at that time.
