I have a customer's Windows 7 Home Premium SP1 PC with two user accounts, one a user/administrator, the other a user/non-administrator. Neither account had a password.
The user/administrator profile has become corrupt and I cannot log on to that account.
Any attempt to fix this via the user/non-administrator account is met with an administrator password request, but as their was no password set, I cannot get beyond that point.
I have tried to activate the hidden Administrator account from the command line, but this is not allowed (presumably as I am in the user/non-administrator account).
I have tried via regedit to restore the backup of the the user profile, but that is not allowed either (again because I am trying to do that via the non-administrator account)
In short the only active administrator account profile has become corrupt and there seems no way round it.
Can anyone help?
