Well, im still running 2004. However, I did notice a new bios for my mobo. Came out in September and I had one from August. So I did the bios update, rebooted, re ran the cmds, rebooted again, and after another image file backup completed, I am starting the 20H2 update again. I'm hoping the BIOS update is the answer, wishful thinking. If not, then I'll restore and try something else, so I'm wide open for suggestions at this point
each time I try a new config, I run these commands. First few times, it fixed corrupted files, now its clean, however I get the same results, so I'm trying again with the BIOS updated.
