Only share your screen with people you know and trust. For the full steps, see how to use Remote Desktop on Windows 10 Home.
Frequently asked questions
Why doesn’t my TV show up in Connect?
The TV or adapter may not support Miracast, or it may be off or on another input. Check that screen mirroring is turned on in the TV’s settings, then try Windows logo key + K again.
How do I share my screen in a video call?
Use the Share button in the calling app you’re using. That app controls screen sharing during calls.
Microsoft’s reference is Screen mirroring and projecting to your PC or wireless display. More help is on our Windows Help & Guides page.
