Benefits of Vista's Hidden Administrator Account

The main benefit of activating this hidden Vista Administrator is so that you have access to an account, which does not suffer from the annoying UAC dialog box. Although it is possible to suppress the UAC with a local policy, there is a lingering fear that security is being weakened. Another worry is that rumours persist that some commands don't work properly if you turn of the UAC.
Linked to the benefit of suppressing the UAC dialog box is the fact that this Administrator account has elevated privileges. What this means is that if your run CMD you don't have to 'Run as administrator' before you get unrestricted access to the command line.
Another benefit of knowing this method is to keep the hidden Vista administrator account as a 'back door', for example, if you inadvertently lock out your main account. Sitting there at your computer, you can never believe that you will be so foolish as to lock yourself out, yet logic dictates that somewhere in the world, someone has just done that: locked themselves out of Vista. Would not they like to know how to activate the administrator account?
Naturally, it is a case of administrator by name and administrator by function, this super user is a member of the Local Administrator's group. In many ways this super Administrator account reminds me of the Unix root account. As I am not a 'professor' of Unix I do not know if you can hide root, but you can hide Vista's administrator account with this command:
Net user administrator /active:no.
