About a month after its launch, Windows 10 has gained widespread acceptance. Microsoft’s latest operating system is now installed on 75 million PCs spread across 192 countries. Yusuf Mehdi, corporate vice president for Windows and devices, shared some more interesting bits of statistics through a few tweets yesterday.

Since its launch on July 29, Windows 10 has been installed on over 14 million PCs in the first 24 hours. Probably the biggest reason pushing Windows 10 adoption is that it is being offered as a free upgrade to Windows 7 and Windows 8.1 users. More fun, of course, seems to be Microsoft’s mantra for trying to recover some lost space after the Windows 8 crash. And, for now, they seem to be on the right track. “Even some devices made in 2007 have been upgraded to Windows 10,” Mehdi tweeted, highlighting the power of Windows 10 to support a wide range of Vista PC configurations. More than 90,000 unique tablet and PC models have been upgraded to Windows 10 It also looks like Microsoft’s digital assistant, Cortana, has a funny bone and has told more than half a million jokes in response to the “Tell me a joke” question (see Russell Peters).

Windows 10 has also seen a rise in popularity in the Windows Store, with six times more downloads reported per device than Windows 8. Owners of Xbox One have also streamed more than 122 hours of gameplay on Windows 10 devices. This will be about 13,360 playthroughs of the original story of GTA San Andreas! Also, a total of 10 million acquisitions combined by Microsoft Solitaire Collection and Minecraft: Windows 10 Edition beta players have been unlocked. Mehdi further tweeted that more than 2000 companies around the world are competing to win the Global Partner Slot in its “Upgrade Your World” program. Through this, Microsoft will provide cash assistance to non-profit organizations. He also thanked Kim Kardashian, Lady Gaga and Dwayne Johnson for their help with the Upgrade Your World program.
