After many years of steady decline they now have completed the perfect pile of steaming garbage! EACH update is broken. And after wasting hours to finally get the crap updates installed, EACH update brings additional problems!

Literally the only answer I’ve found to stop this download. It was stuck on 13% on download for ages and I couldn’t get it to stop, restarting the windows update through run was the fix, thanks.

Run Disk Cleanup as admin so it cleans windows update files. Restart the computer and run the update again.
