Microsoft is rolling Windows 10 out in phases, but the company just announced that over 14 million devices are all running its latest operating system. In a blog post, Windows marketing head Yusuf Mehdi says that Microsoft has "many more upgrades to go" before everyone with a reservation gets their copy through. Those who reserved ahead of time will be prioritized.
If you haven't yet decided to make the switch, though, you can still do so through the Get Windows 10 app on your PC. Windows 10 is the first major version of Windows to be made free for most consumers, so Microsoft can expect a faster upgrade pace than usual — especially considering how much of an improvement 10 is on 8.
