Firefox/Firebug User: Wrong. Download Firefox and Firebug and you'll see why Firefox essentially pwns Internet Explorer.
However, it is possible to *disable* access to IE using one of the following methods:
1. Select "Set Program Access and Defaults" from the Start menu. Uncheck each browser that you would like to disable access to.
2. From the Add/Remove Programs applet in the Control Panel, select "Add/Remove Windows Components." Uncheck the checkbox next to IE.
