Microsoft today announced Windows 10 is now installed on over 110 million devices. It took the latest and greatest operating system from Microsoft just 10 weeks to enter the 9-digit range.

The milestone was revealed at the company’s Windows 10 hardware event in New York City. Previously, Microsoft had shared that 24 hours after its July 29 launch, Windows 10 was installed on more than 14 million PCs and that four weeks after launch, Windows 10’s install base passed 75 million PCs.

As Microsoft loves to tell anyone that will listen, Windows 10 is a service. That means it will be updated with not just fixes but new features in the coming months and years. Windows 10 was built in a very different way than its predecessors. And it is still being built.

Microsoft is aiming to have 1 billion devices running Windows 10 “in two to three years,”¬†though that includes not just PCs, but smartphones, consoles, and other devices as well. Indeed, at the event today Microsoft shared details about its latest devices: Lumia 950, Lumia 950XL, Lumia 550, Surface Pro 4, and Surface Book.
