Windows 10: “Select account” BSOD but no accounts to choose from

I went to restart my Windows Pc after deleteing some files to make room for storage I think I may have accidently deleted a sysytem file but it says “Select account” But there are no accounts to choose from and under that it says “You need to sign in as an administrator, but there aren’t any administrator accounts on this PC.” And at the bottom it says “Forgot your password or dont’t see your account?” Then when I click that it says reset PC and that just brings me back to the screen again what do I do to fix this?

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:

 

Google account and old smartphone

you can't. once it is registered to an account it stays on that account, however if you turned off sync and removed the account from the phone, it will never sync to it.

 

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
