LIke an idiot, I tried to enable automatic login without credentials via netplwiz. http://windows7news.com/2009/02/01/automatic-logon-into-windows-7/
I turned off Users must enter a user name and password to use this computer.
Unfortunately, this turned my standard user account (Home Users Group) into a guest account.
Now I can't do anything beyond a guest user can do, and I am effectively locked out of using RunAs administrator. I can't activate the hidden Administrator account (acces denied).
What do I need to do to go back? Am I really screwed and have to reinstall the OS?
Thanks in advance.
