Microsoft announced on its blog today that Windows 10 has reached 75 million instals on devices.

Yusuf Mehdi, Microsoft corporate vice president of marketing for Windows and devices, also shared the milestone on Twitter. He also shared that over “122 years of gameplay” have been streamed from Xbox One consoles and Windows 10 devices.

Included in the announcement were the stats that 10 million achievements have been unlocked on the Xbox One and that app usage has gone up 6 times since the Windows 10 update.

Besides the addition of game streaming from an Xbox One, the Windows 10 Xbox app also includes features which allow screenshotting, cross-platform play, and GameDVR.

Windows 10 launched late July and was meant to be an upgrade from Windows 8. The upgrade is free for Windows 7 and 8 users for the first year after launch.
