If Microsoft enabled Windows 10 PCs to stream games to Xbox One, keyboard and mouse support would definitely follow.
When Windows 10 releases in the coming days, anyone who owns an Xbox One will be able to stream Xbox One games to any PC running the new OS. As for the other way around, Microsoft always said that it’s something it’s looking into.
Of course for that to be fully functional, Xbox One will need to fully support keyboard and mouse as an input device. Xbox boss Phil Spencer knows this, and has recently reiterated on Twitter that he likes the idea, but doesn’t have anything to announce.
He did however add that should it happen, keyboard and mouse support would need to be there.
Keyboard and mouse support could be added to Xbox One and still be limited to streaming situations, preventing users from gaining an advantage in multiplayer games.
