Windows Update settings on Windows 10

Windows 10 version release history tracker

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

UPDATED 3/19: 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).

Windows 10 version 1809 (October 2018 Update) history

Windows 10 October 2018 Update (version 1809) is the sixth major release and the second semi-annual update available starting October 2, 2018.

In this section, you’ll find the list with all the quality updates and links to find out the details about each release. The first quality update for Windows 10 version 1809 will arrive on October 9 to fix and improve the latest release.

If you have already installed the new feature update, then the latest version is Windows 10 build 17763.55. If you’re a tester, then the latest version is build 17763.379. However, both versions now includes the fixes to prevent data deletion during the upgrade process.

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 a not 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.
