Heh it look like WSUS has a problem displaying windows version correctly. I logged into one computer I did a winver and it gave me version 21H2 19044.1706 while in wsus console this computer has version 10.0.19041.1682
Again one more computer that has been updated yesterday from microsoft online and is up to date with 21H2 onboard, and in WSUS version it have 10.0.19041.1682.
What's wrong with my WSUS?
