How does Xbox Play Anywhere work?Vevo Digital
Xbox Play Anywhere is the service that allows you to play a game both on your Xbox One console and a Windows 10 PC.
When you buy an Xbox Play Anywhere digital game through the Xbox Store, the Windows Store or any third party reseller, it’s yours to play on both Xbox One and Windows 10 PC at no additional cost. To take advantage of this service, you will need to have installed the Windows 10 Anniversary Edition update on your PC, as well as the latest update on your Xbox One console. Then, simply log into your Xbox Live/Microsoft account and your Xbox Play Anywhere games will be available to download. On your Xbox One, games will show as “Ready to Install” under “My Games and Apps”. On your Windows 10 PC, games will appear in “My Library.”
