An account on my Windows 7 installation cannot have its type changed from an administrator to a user account.
I tried to change it using the cmd and I'm getting these messages:
>net localgroup administrators AccountName /del
System error 1377 has occurred.
The specified account name is not a member of the group.
>net localgroup administrators AccountName /add
System error 1378 has occurred.
The specified account name is already a member of the group.
I recently used a livecd to change this account to an administrator since I had forgotten my password to another account, and now I need to change it back.
What should I do?
