A new Windows 11 Insider Preview Build 22499 has been released to Dev Channel on Nov 10, 2021. I missed previously two builds with Dev Channel due to migrated Win11 to the Beta Channel on my production environment laptop,😂 but still I’m testing the Builds from Dev Channel just with another device. Let’s see what’s new with this Build 22499. 🐱👤

Sharing app window directly from Taskbar with Microsoft Teams
Microsoft announcing a new experience with the ability to quickly share the content from opened app window directly from your Taskbar to your meeting calls. With this experience, you can quickly share any opened program window to attendees during a Teams call reduced the interruptions.

Whenever you joined a meeting with Microsoft Teams, says you have an updated version of presentation would like to share with attendees to discuss, simply just hover over the cursor to the PowerPoint app window on the Taskbar then click “Share this window” to bring to the meeting session. When you completed the sharing just hover to the window again then click “Stop sharing” to end the sharing with the presentation easily.
Note, as per Microsoft announcement this experience so far only roll out to a subset of Windows Insider with Microsoft Teams (not the Home version). And 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.
A new “Shipped Windows 11” badges roll out to the Insiders in Feedback Hub app.
