As I type this news from a Windows 10-powered desktop PC, news has landed that Microsoft has hit a milestone of 400 million active devices running Windows 10.
It has taken Microsoft around 14 months to hit 400 million users on Windows 10 since its launch, with 100 million users poured into the Windows 10 pool since May 5. Towards the end of March, there were 207 million active devices running Windows 10 - now remember, "active devices" is a considerable team of products.
We're talking about desktops, laptops, tablets, phones, Surface Hubs, HoloLens devices, and more. Microsoft isn't quite at its 1 billion goal yet with Windows 10, but the latest desktop OS is definitely the fastest-growing Windows platform in history.
