Versioning

Windows 10 version release history tracker

Windows Update History information helps you know exactly what's the latest version of Windows 10 available.

Windows Update settings on Windows 10

UPDATE 5/18: Microsoft changed the way devices get updated when introduced the idea of Windows as a Service (WaaS). This means that starting with Windows 10, and moving forward, instead of waiting years to get an entire new version, we get smaller incremental updates twice a year.

The caveat with this approach is versioning becomes more confusing, and it makes difficult to track what’s the latest version number of Windows 10. In the past, it was easy to distinguish the different versions because of the number next to the name (e.g., Windows 7 and Windows 8).

Now you could be running an entire new version of the operating system, but it continues to be Windows 10. The only way to know if your PC is up to date is by knowing exactly the latest version number of Windows 10 available and manually checking the version on your device.

In order to help you stay up to date, here is the latest Windows 10 update history information (including for devices enrolled in the Windows Insider Preview).
