So you thought there were 800 million Windows 10 Devices that will get Microsoft’s most recent out-of-band emergency patch? Think again. As the company announced on Twitter today, Windows 10 now runs on over 900M devices.

That’s a bit of bad timing, but current security issues aside, the momentum for Windows 10 clearly remains steady. Last September, Microsoft said Windows 10 was running on 700 million devices and by March of this year, that number had gone up to 800 million. That number includes standard Windows 10 desktops and laptops, as well as the Xbox and niche devices like the Surface Hub and Microsoft’s HoloLens.

As Yusuf Mehdi, Microsoft’s Corporate Vice President of its ‘Modern Life, Search and Devices’ group, also noted, the company added more Windows 10 devices in the last twelve months than ever before.

Come January 2020, Windows 7 is hitting the end of its (supported) life, which is likely pushing at least some users to move over to a more modern (and supported) operating system.

While those numbers for Windows 10 are clearly ticking up, Microsoft itself famously thought that Windows 10 would get to 1 billion devices by the middle of 2018. At this rate, Windows 10 will likely hit 1 billion sometime in 2020.
