I recently approved 20H2 in WSUS. I looked for the most recent to approve which was a December 3, 2020 release of En-US x64 Business Editions. Strangely, the newest version of the 20H2 update doesn't say anything supersedes it, but it also doesn't supersede anything even though I can see previous 20H2 versions in WSUS. The November 9, 2020 release says it supersedes a previous release and no update supersedes it. Not sure why the December 3 release didn't supersede it.
Most clients liked the December 3 version that I approved, but 1 client in my pilot group reported to WSUS saying it needed it, but would never find it and try to install it. As soon as I approved the November release the client happily started downloading it.
What's up with these 20H2 releases? Should I leave both versions approved? I have a Windows Update Log if anyone wants to see it, but it looks fine to me.
