Error 0x80242017 when installing KB5004945 from WSUS (but not from Microsoft)
I have several clients running Win 10 v20H2 that are failing to install the update "2021-07 Cumulative Update for Windows 10 Version 20H2 for x64-based Systems (KB5004945) from our WSUS server with "...
- I posted a reply with the answer and it was removed. No idea why. It's a service stack update issue. If a computer missed the May cumulative update then KB5004945 won't install in my experience. The May CU included the latest SSU. Without it, you get 0x80242017
It seems like there have been corrupted files on the system which has been fixed, did you manage to update after running the SFC command?

If yes, just for test try remove one of them from the Domain and see if the problem persist?
Make sure report this issue through the Feedback Hub app.- Yes, they are domain-joined. I tried removing a client from the domain, then re-importing the WSUS registry settings to point it back at the WSUS server, and it still gives the same error (0x80242017).
