How can I logon to Administrator account in Vista OS,thanks?

Answer 1

In Windows Vista, you do not have immediate access to the Admin Account. When logging into Windows Vista, you do not have the option of using this account.

From the Start menu, simply right-click on Computer and choose Manage. Next, expand Local Users and Groups and select the Users folder. The final step is to right-click on the Administrator login and choose properties. Clear the Account is Disabled checkbox and you have now enabled your Administrator account.

Answer 2

With Windows Vista, the Adminstrator account is diabled by default and hidden on the Welcome Screen and even in Safe Mode. And it requires no password to log on. This is done to provide a way to recover if you somehow manage to delete the last computer adminstrator account.
