Will Chromecast work if GateKeeper locks computer?

Yes. If you are casting your screen using Google Chromecast, the cast will continue to run even when GateKeeper locks the computer. This is because GateKeeper triggers the standard Windows lock screen, which restricts user interaction but does not stop running applications or active casting sessions.

What Happens When GateKeeper Locks the Computer

When GateKeeper locks the workstation:

• Windows switches to the lock screen

• The user cannot interact with the desktop

• All active applications continue running in the background

Since Chromecast mirrors content at the operating-system level, it continues streaming whatever was already active before the lock occurred.

This behavior is similar to virtual meeting applications or media playback, which also continue running during a lock screen event.

What You Can Expect During a Cast

While the computer is locked:

• The Chromecast session remains active

• Audio and video continue playing as usual

• The content displayed on the TV or cast device remains uninterrupted

• You cannot control the cast until you unlock the computer

GateKeeper does not pause, close, or interfere with casting functions. It only controls workstation access.

When the Cast Might Stop

Although GateKeeper itself does not interrupt Chromecast, the cast may stop if:

• The application playing the media closes

• The network connection drops

• The computer enters sleep mode

• A corporate network policy ends casting sessions when the device is locked

These conditions are unrelated to GateKeeper’s locking function.

Summary

• Yes, Chromecast continues to work when GateKeeper locks the workstation.

• GateKeeper only locks the screen and does not interrupt running applications.

• The cast will play normally until you manually stop it or unlock the workstation to take control.
