The latest Windows 10 update, after restart, doesn't let me log in to my computer. Windows seems to be stuck in a Windows Repair Mode loop, where every option simply results in Windows restarting and winding up at the same place.
A complication is that while "Continue to Windows 10" results in a restart, "Troubleshoot" and all the options it gives say "You need to sign in as an administrator account to continue, but there aren't any administrator accounts on this PC." Absurd situation.
The "forgotten your password or can't see your account?" option results in a restart and Windows Repair.
I've also tried booting Windows from the installation USB flash drive, but no luck.
