Microsoft looks to be using those in its Insiders test program to test native Xbox One games on Windows PC.
There are users currently testing and improving Windows 10 PC gaming, equipped with a free copy of State of Decay: Year One — and the interesting thing here is that said free game looks to be downloading from Xbox servers rather than PC ones.
“Instead of downloading from the Microsoft Store server, serverdl.microsoft.com, where all content comes from including PlayAnywhere titles, the game downloads from assets1.xboxlive.com,” a report from Thurrott states.
Microsoft’s description of the testing seems to be purposefully vague, but it has many lead to believe that Microsoft is testing Xbox Play Anywhere functionality on PC, perhaps meaning the entire Xbox One Play Anywhere library will soon be supported on Windows 10.
“We’re excited to bring technology tailor-made for gaming to Windows,” Microsoft declared. “Help us validate these systems work as expected, and play State of Decay for free (limited time only!). Just tell us about any problems you encounter with installing and launching the game. You’ll need to have a PC on a version of Windows 10 from the Windows Insider program that is 18329 or higher in order to participate in this playtest.”
Microsoft has yet to confirm these suspicions; we’ll keep you posted.
