Microsoft is edging closer to its 1 billion goal for Windows 10. The software giant is revealing today that Windows 10 is now running on more than 900 million devices, a significant jump from the previous 800 million figure achieved earlier this year. Microsoft says there have been more new Windows 10 devices in the last 12 months than in any previous year since Windows 10 was introduced back in 2015. This figure includes traditional PCs, laptops, tablets, and even devices like the HoloLens and Xbox One.

The momentum is clearly down to the end of support of Windows 7. Microsoft is planning to drop Windows 7 support in January 2020, and most businesses are moving to Windows 10 instead. The jump to 900 million comes just six months after Microsoft achieved 800 million devices on Windows 10, and if this Windows 10 upgrade momentum continues, then Microsoft could pass the 1 billion milestone in the next six months.

Microsoft previously hit 700 million Windows 10 devices in September 2018, followed by 800 million in March 2019, and now 900 million in September 2019. Windows 10 also passed Windows 7 popularity earlier this year, signaling a shift away from Microsoft’s previous popular desktop operating system.

Of course, Microsoft had been planning to get Windows 10 running on a billion devices within three years of its release, but the company soon extended that timeline after it was clear that Windows Phone wasn’t working out. Now, it looks like Microsoft will achieve its 1 billion goal with Windows 10 within five years of the operating system’s release.
