Windows 11 is making it easier to share your screen in Microsoft Teams and other video calls

Microsoft will soon add a new Microsoft Teams integration to Windows 11. Microsoft has begun testing a new feature in Windows 11 that allows Teams users to hover over open taskbar windows and share their contents on a Microsoft Teams call. This feature will make screen sharing much easier for Teams and other communication apps in Windows 11.
Microsoft will be testing this first with Microsoft Teams at work or school, rather than the Windows 11-based consumer version. Amanda Langowski, Microsoft's Windows Insider Program head, says that not everyone will be able to see it immediately with their Teams calls. "We will bring this to Chat using Microsoft Teams (Microsoft Teams at home) later."

Zoom, Slack and other users will be able to add this integration at no cost

This isn't just for Microsoft Teams. Langowski explains that other communications software can add this capability to their apps. "The ability to share your meeting calls applies only to your current meeting calls."

This means that apps such as Zoom and Slack could integrate this functionality into their apps. It will make it much easier for Windows 11 users, who can now share what's on the screen with one another during video calls. Although it is not yet clear when Microsoft will release this functionality in Windows 11 due to the timing of testing, it is likely that it will appear in early 2022.

Microsoft is only testing it with a small subset of Windows Insiders. Therefore, having Windows 11 Dev Channel builds installed does not guarantee that you will be able test it.
