Downloading and applying to all production PCs. So far, so good. Fast download, less than 2 minutes to restart notification. Quick post-reboot handling, too. Hope all machines go this smoothly.

What is the recommended fix for correcting 661?
very fast download and installation.. not as usual
but i still monitoring if something goes wrong after update
KB4586853 on Nov 12, was the update to bring you to .661 and KB4586781 on Nov 7 to .630. If you have a system image backup before Nov 12, 2020 (full, differential or incremental) you can use it to go back to .630 or you can use the enablement package in the following link below using the .CAB file to have a try at going to .662 from previous build. Contrary to others not able to go from .661 to .662, it has worked for me.
KB4562830 Enablement Package Feature Update to Windows 10 version 20H2
Successfully installed KB4592438 via Windows Update on two machines.
From 20H2 b19042.630 -> 20H2 b19042.685
Took about 15 mins each machine.
Older MBR disk system found / fixed corruption after the update when I ran sfc /scannow
Newer GPT disk system reported no errors/corruption after the update when I ran sfc /scannow
Both systems stable - will see how it goes.
