Trouble users have tendencies to do all sorts of things to mess up a computer. One of the more common things I have seen is for a user to set a supervisor password on Internet Explorer, making it so that they control what you can and can’t access on the internet from that computers browser. The best solution for this problem (besides hitting the user over the head) is to simply use the registry to remove this supervisor password.
Click on Start, choose Run, and type “regedit” to access the Windows registry editor. Once here, on the left hand side of the screen, browse to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version\Policies, and click on the Ratings folder. Once here, look at the right side of the screen, find the entry named Key, click on it, and press the delete key. Close the registry editor and the content advisor password will be removed. Restarting the computer should result in your browser being unlocked.
