Microsoft appears to be bringing Xbox game compatibility to Windows


May 2, 2013
Microsoft has been working on stepping up its PC gaming efforts for a few years now. Initiatives like Play Anywhere have seen first-party exclusives launch simultaneously on both platforms with save files crossing over. There is more to come though, and the latest Windows Insider update gives us a peek at what that is.

Earlier this year, Microsoft curiously offered State of Decay for free to those testing the most recent Windows Insider build. Normally, Microsoft’s PC games pull from the Windows 10 store server, but this particular version of State of Decay came from the Xbox server instead. People have been diving deeper in to this over the last few weeks, discovering more details on GameCore, an upcoming feature for Windows 10.
