It is very possible that later non-security updates are intentionally causing the difficulties that you are describing.

The reports that I am reading seem to indicate that it actually is security updates to Windows 10 version 22H2 that have been causing difficulties for many. Supposedly patches are being released, but it makes me wonder what Microsoft is up to.

So...

THEORETCALLY if I wait until, say, next weekend and then download (create) a new Win 10 Pro bootable USB flash drive, and use that to boot the machine, it may boot correctly, and then maybe I could roll back the Sept. update on the C: drive?

I’ll try safe mode in the Win 10 Pro machine again, too, once I get this WIN 11 Pro machine all dialed in. The Dell Repair Software was telling me there was no restore point to go back to, which seems impossible, as I’d created one manually about 2 months prior, and there should have been even earlier ones, too. I know they get overwritten as the space allocated gets used up, but there used to be several listed. WTH. (eye roll)

You have a lot of company.
