Windows 10: How do I activate my windows account after a computer reset

I reset my computer after having some issue's. After the reset it say "we can't activate Windows on this device because you don't have a valid digital license or product key".I got my product key using the command prompt and comes up with a window saying the same thing "we can't activate Windows on this device because you don't have a valid digital license or product key". I have tried it several times and made sure I put it in correctlyI don't know what else to do. from everything I read this should be working and it's not.

Strange Windows 10 User Account issue.

Unfortunately I had done those steps numerous reboots, it just, reappears for no good reason. The base account isn't even a Microsoft account, it's a local account.

I haven't quite tried the built in administrator account on W10, but so far in my experience on my own computer, the built in account seemed to have absolutely no more control than I did on my own.

It's just strange, I go in, it warns me twice about deleting the account, then it's gone. Reboot, and it's back?

EDIT: Just to specify, both command line and Netplwiz both say only HIS account exists on the computer, it doesn't list this rogue account. This is what I meant in my first post about the fact that even Windows doesn't seem to believe it exists, HALF the time. *Frown
