Looks like Microsoft’s aggressive moves to drive adoption of Windows 10 – including making their newest OS free to upgrade to, as well as some questionable methods to passively update people’s computers – have paid off, because less than a year after it launched, Windows 10 is now already being used by almost half of Steam’s massive userbase.

According to the latest statistics revealed by the company, almost 45% of all PC gamers are now using Windows 10- this makes it the most used OS on Valve’s service by any metric, and it also indicates that by and large, PC gamers are upgrading to Microsoft’s new offering en masse. Windows as a whole has 96% of all PC gamers, while the remaining 4% of them are divided between Mac OS X and Linux.

On the whole, this should be great news for Microsoft, especially since their own UWP, Windows Store, Xbox Anywhere, and PC gaming efforts are all tied intrinsically to Windows 10- more people on Windows 10 means more of a base to market these efforts to.
