Hello. I got 21H1 installed on a machine but on reboot, it asked for my PW, which I typed in. It was refused. Then the fun began ! It, the machine, asked me to change to a new PW, that was fun, it would not accept anything at all. I then hit the "use another way to do this" and it sent me a code to enter. I was to find it in my mail. Get this, inop machine. I used a neighbour's machine and retrieved the code after a second request after not finding them, guess what . . . they were in the spam file. OK, back home with the code still not accepted. Luckily I had a clone and got the machine running.
Is this going to be the new way to get Updates installed ? I enter PW using C&P from a USB device and they always worked before. What has MS added to this Update that needs a PW input on the first boot ?
