Solved

In case anyone else reads this thread, this was an free upgrade from Win7 by Microsoft that I accepted. I was obliged to provide a Password. My PC is part of a home network of 3 PCs. Because all stored network files were in the Win10 control, when I got the Critical Error, all PCs were denied access to the files. I shut down, restarted and pressed F8 then Esc. It gave me sufficient access to Change Password that I removed it. Then when I restarted the PC, it was OK. Scary though! It's been fine since.
Thanks, Mr. Kees.
