How to Turn On or Off “Share Any Window” from the Taskbar in Windows 11

Want to quickly share a window during your meeting without switching between apps? Windows 11 lets you share open app windows right from the taskbar! This guide will show you how to turn this feature on or off in just a few simple steps.

What Is This Feature?

Starting with Windows 11 build 22499, Microsoft added an easy way to share any open app window directly from your taskbar during meetings. This works great with Microsoft Teams. You don’t have to keep switching between apps to share your screen or stop sharing it anymore.

Here’s how it works when you’re in a Microsoft Teams meeting:

• Hover your mouse over an app icon on the taskbar.
• A small preview of the app window pops up.
• You will see a new button like “Share this Window” to share it instantly.
• To stop sharing, hover again and click “Stop Sharing.”

Even if you’re showing a full-screen PowerPoint, just move your mouse to the bottom to bring up the taskbar. Then you can manage sharing without bothering your viewers.

Other apps that do meetings or chats can also add this sharing feature.

New in Windows 11 Builds 26100.7309 and 26200.7309

Hovering over taskbar icons now also shows a “Share with Copilot” button. This lets Copilot Vision look at your app’s content and give helpful suggestions.
