More than 40% of Windows users are still on Windows 7, an operating system which is leaving extended support in only 3 months.

One would hope the deadline would encourage companies to upgrade their PCs, and the latest indication from the official Windows 10 installed numbers suggests that is exactly what is happening.

In September 2018 Microsoft confirmed that Windows 10 is now installed on 700 million actively used PCs. In March 2019 this was updated to 800 million.

Today Microsoft confirmed that there are now 900 million Windows 10 users.

The number was confirmed by  Corporate Vice President of Modern Life & Devices Yusuf Mehdi who posted:

#Windows10 is on more than 900M devices! Thanks to our customers, we added more new Windows 10 devices in the last 12 months than ever before. From PCs to HoloLens to Xbox to Surface Hub, Windows continues to power innovation—with more to come next week!

The most interesting part of the tweet is the suggestion that Windows 7 users are upgrading faster to Windows that they did when the operating system was free in 2015.

The number is still shy of Microsoft’s 2015 target of 1 billion devices running Windows 10 by 2018, but given that the PC installed base seems relatively stable it appears they will get there eventually.
