On a windows xp computer, I tried the trick of logging in as the "SYSTEM" user. I found a setting that allowed me to see (and modify) all the users, including "LOCAL SERVICE" and "SYSTEM". Now I want to find it on a windows 7 computer but I don't know how. I simply can't remember how I got to the settings in xp.
NOTE: by user management tool, I do not mean the user accounts page in control panel.
