Xbox on Windows - Free
With Xbox on Windows, the Windows 10 laptop or desktop you already own is also a great Xbox One accessory.
Xbox on Windows is a free app that you can download from the Windows Store if it isn't already installed on your PC. It turns your laptop or desktop into an Xbox One companion. Use the app to browse the Microsoft Store for new Xbox games to play, keep track of what your friends are playing, track your Achievements, message friends and look at video clips from gamers you don't know. Connect an Xbox Wireless Controller and the Xbox app will stream footage from a game on your console so that you can play anywhere in your house.
If your PC is powerful enough, Xbox on Windows turns it into another Xbox. Any Xbox Play Anywhere game in your library automatically unlocks a PC version for you to play. Your progress syncs between this new version on your PC and your Xbox One every time you play.
