Much appreciate the advice and suggests and sorry to be a PIA, but.........

These are the accounts, and as you can see, they both say Administrator.

But when I attempt to change the upgrade settings, this is the message I receive and I don't understand why or what I can do.

I have used the CMD to make account active, Netplwiz is unchecked to boot to desktop without password, etc.

If I go to this screen, it is locked on the top account and neither mouse nor arrow keys move the highlight.

So I am no further forward in booting to the desktop with no user input although I now only have to press enter at the prompts rather than enter any username or password. But I don't even want that. What next?
