Windows 10 version release history tracker

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

UPDATED 12/12: 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 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 (for example, 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). If you want to check what updates are already installed on your device, use these instructions.

Windows 10 (version 1709) Insider Preview build history

Alongside the public versions, Microsoft also has the Windows Insider Preview Program, which allows anyone to download pre-release version of Windows 10 to test new features and changes of an upcoming update.

The program is divided into rings, including the Slow, Release Preview, and Fast ring.

The Slow ring lets users get pre-release versions of Windows 10 that are very stable, but may have some bugs and things not working. The current available version is Windows 10 build 14931, which is for the Anniversary Update.

The Release Preview ring lets users get pre-release versions of upcoming cumulative updates of a particular version of Windows 10.

The Fast ring lets users get pre-release versions of Windows 10 with the latest features and changes. Updates released through this ring are buggy, some features may not work, and it’s not a version recommended to run on a production machine. The current available version is Windows 10 build 16299.15 for PC and Windows 10 Mobile build 15254.1 (Windows 10 Mobile Fall Creators Update candidate) for phone.
