Inside Windows Vista,an administrator account exists just like Windows XP.It is not part of administrator group.But it is a super administrator account,just like root in unix.It is disabled and kept hidden.Microsoft doesnot discloses this for security reasons.Infact Microsoft said Windows Vista doesn`t have any administrator account like Windows XP.

Also you will see that this account is not subjected to User Account Control like other normal administrator account.You will not see any UAC prompts while making changes to the system.

So how enable it.Let me start:-

Run command prompt(run as administrator)

Type the following commands
Net user administrator /active:yes

Now you will an administrator account on your login screen

To disable it,use this command Net user administrator /active:no
