Windows 10: Removed my desktop device from my microsoft account and now my windows account is stuck as...

so basically what happened was I removed my desktop from my microsoft account and it revoked my administrator privelage from my computer, my computer only has one account and it is not an administrator, I have been trying to find a fix but everything I tried resulted in the UAC popping up with the message "To continue, enter an admin username and password" the yes button is greyed out and there is nowhere I can put an admin password. And there is absolutely no way for me to change it from a user to an administrator.

Remove account

I suggest you backup your personalized files first before removing the account.
To delete an account, follow these steps:

1. Press WIN + X keys and click Command Prompt (Admin) from the menu.
2. Type the following command and press Enter. Replace test with the name of your sister's account. Code:

 

Unknown devices on my Microsoft account

Hello Flemmingk,

Could these other devices be from friends that you may have signed in to your Microsoft account on for something?

Either way, you can remove these devices.

Afterwards to be safe, I would recommend to change the password of your Microsoft account, and enable two-step verification if you haven't already.

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
