Microsoft revealed the newest Windows 10 installation number via a tweet by Corporate Vice President of Modern Life & Devices Yusuf Mehdi.

Microsoft's "monthly active devices" metric is for devices that have been "active" in the past 28 days. It includes Windows 10 on PCs, tablets, phones, Xbox consoles, HoloLens and Surface Hub devices, and includes all of the various feature updates of Windows 10. 

Microsoft's self-stated goal in 2015 was to have Windows 10 running actively on 1 billion devices within two to three years of its initial release in 2015. Microsoft officials conceded in 2017 that it would take the company longer than that to hit the 1 billion mark, likely as the result of Microsoft's failure to get phones running Windows 10 to gain traction.
