Windows 11 and 10, comparedWhat’s notable about this milestone is that Windows 11 reached 1 billion users faster than Windows 10 did. While Windows 10 took approximately 4 years and 8 months to hit this number, Windows 11 did so in just under 4 years and 4 months. That said, it’s still slower than what Microsoft had anticipated for Windows 11. The company wanted to bring Windows 11 to a billion users within 3 years of its release. Although some Windows 10 PCs that didn’t meet the minimum requirements for a Windows 11 upgrade were replaced with newer devices, lots of private home users in particular are still sticking with Windows 10.
