Windows 10 version numbers – and how they actually show up in SCCM when added as WIM

Windows 10 version numbers when running within Windows are fairly well known are are available from 

However, when adding the WIMs to SCCM as OS images, the numbers don’t match up. When aligned with the absurd method of obtaining Windows 10 21H2 which does not give you any information on which version your getting  (detailed here – ) it can create confusion/concern that the correct version has actually been downloaded / imported.

In order to allay this (somewhat) – i have imported each version into my SCCM environment and have a screenshot of the results below.

As you can see – the version numbers of the images do not match up with the version numbers of the OS’s they contain….

And when compared to actual versions within Windows
