What is game streaming?

Game streaming is the ability to play Xbox One games remotely from your Xbox One console on any Windows 10 PC on your home network.

This feature allows you to leave your living room and play your favourite Xbox One games anywhere with access to your home network.

Game streaming uses the power of the Xbox One console to manage the game.

Your Windows 10 PC becomes a remote second screen so you can roam freely around your home while continuing to enjoy your Xbox One console and games.
