I just learned how to unlock the hidden administrator account in Windows Vista from pcwizkid . I always wonder why there was not an account called Administrator in User Accounts in Control Panel, but I see the account when I set my permissions for registry keys and files. Now I know Vista hides it by default.
First, you have to run your command prompt as an administrator by right clicking the command prompt shortcut, and picking the “Run as administrator” option.
Run Command Prompt as administrator
Type “Net user administrator /active:yes” without the qoutes, and press enter in Command Prompt
Net user administrator /active:yes
I recommend going into Windows’ Control panel and User accounts, and setting a password for your Administrator Account since anyone can use this trick to hack into your computer with a limited account or possibly guest account by enabling the Administrator that does not have a password by default account from their non-admin account. This seems like somewhat of a security risk since when I enable my admin. account it was not password protected. Learn how to make a password for your administrator account by reading my tutorial on making a user account password from user accounts.
