This seems to be a common issue, but I haven't found a report of it on a new install of 20H2.
I've tried Troubleshooter, sfc, Dism but all still end up with the Cumulative update installing to
30% then Restart
35% Restart
"Couldn't complete updates
Undoing Changes"
Restart
and cycling through that 3 times.
Checking Updates, there is the same persistent warning that the Cumulative Update has failed.
How do I fix this please?

Many thanks! I have been wondering whether to do this - a complete new install.
It will mean reinstalling all the applications etc, but I can live with that - a stitch in time and all that.
One thought first, though: I decided to fit a second 1TB SSD in the new build, so that I can clone a backup image onto it once the original drive is running smoothly, and Windows is updating ok; I haven't even formatted that yet. Does MS allow me to install a fresh Win 10 onto that while the other drive is still active? That way I can check that the updates will work on the new drive before going to all the trouble of saving data files, and reinstalling Cubase, Thunderbird etc on the current boot drive.

Thanks very much for this advice. I tried a reset saving Apps and data - in vain. So then reset using Cloud download, as you suggested, removing everything having backed up all data to the 2nd SDD and a USB stick.
Once Windows was running and configured I installed nothing until I'd used Windows Update several times. All seems to be in order, and updates are complete.

Having installed the list of updates it displayed, it reported Up To Date, but I checked for updates (this has happened before), and sure enough there were more.... Defender, I think it was.
