Following the release of Windows 10 for PC, reports have indicated Microsoft will begin rolling out versions for phones, Xbox One, HoloLens, and other devices "later in 2015."
Microsoft announced in January 2015 that Windows 10 would be integrated into Xbox One by way of a future update. Xbox boss Phil Spencer assured fans at the time that when the Windows 10 Xbox One update arrives, it won't morph the games console into an enterprise-centric device.
in addition to allowing Xbox One owners to stream their games to Windows 10 PCs, the operating system will facilitate cross-platform play in upcoming games such as Lionhead's upcoming RPG Fable Legends.
