Windows 10 version release history tracker

UPDATED 6/22: 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 vrsions 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 1803 (April 2018 Update) history

Windows 10 April 2018 Update (version 1803) is the fifth major release and the first update out of two rolling out in 2018 available starting April 30, 2018.

Below 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 1803 was build 17133.73, but due to a blocking bug, Microsoft created build 17134.1 making build 17134.5 the actual first official quality update for the April 2018 Update. 

The latest version is Windows 10 build 17124.112.
