I followed advice on: http://www.mydigitallife.net/2006/07/19/missing-or-no-security-tab-found-in-windows-xp-professional/ to try to get my security tab to show so that I can control access of IE. I tried the direction for "my computer" but the option did not show on my list. I tried the registry key, but the key was not in my registry. I am using XP home edition. Do I need to creat a new registry key in order to control the security tab on IE explorer? If so, how do I do this?
