Windows 10 Installed On 75M PCs After Four Weeks

Windows 10 has only been available for four weeks, but the new operating system is already installed on 75 million computers. Yusuf Mehdi, Microsoft's Windows marketing chief, revealed the install figure. Mehdi also said 90,000 unique PC and tablet models in 192 countries have been upgraded to Windows 10 since the OS' release.

Already, Xbox One owners have streamed 122 years worth of gameplay from their console to Windows 10 PCs.

Windows 10 is still being rolled out in waves, but there are ways pretty much anyone can get it immediately.
