The latest builds of Windows insider indicate that Microsoft is working to unify the infrastructure of Windows 10 and the Xbox OS. This makes it possible to play Xbox console games on PCs with Windows 10, which has already been demonstrated with the survival action game State of Decay. 

This is not a good development for PC Gaming as they could become console standardization running on the PC. By making this 'port' compatibility, basically, Microsoft seems to indicate that it would like to release console games on the PC. 

Microsoft has not announced these changes just however in Windows 10 Preview Build 18334 the company implements a free version of State of Decay to download to report issues. When downloading this (trial) version, the game is no longer sourced from the Microsoft Store servers, but rather from the Xbox Live servers, which typically ship only pure Xbox titles. 

The installation file obtained through this server uses the .xvc file format developed for the Xbox One but plays the normal game through PowerShell. The conclusion is obvious: The Xbox version of the Survival game is playing, not the PC version. Ergo, the games are emulated.

So in the future, chances are that if you purchase a PC Game in the Windows Store, you might end up with an emulated XBox One version.
