Versioning

Windows 10 version release history tracker

This info will help you know exactly what's the latest version of Windows 10 available.

Windows Update settings on Windows 10

Microsoft has 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 a new version, we get smaller incremental updates once or 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 checking the version on your device to know if you need to update.
