Is there is a way to make UAC prompt for a password that is not the password of any of the users on the PC? Is there a way to set a UAC password so that not even any of the administrators could successfully trespass UAC?
The background is that I have a computer whose default (and only) user is the administrator and I want so set it up so that for any major change to the PC, a password is required without adding a new accout.
