There are three ways to access the setting (not a big surprise, since Microsoft really wants you to use IE 4.x): right-mouse-click the Internet Explorer icon on your desktop and select Properties; or double-click the Control Panel's Internet icon; or select View, Internet Options inside an IE window. Regardless of how you get there, click the Programs tab and select Internet Explorer Should Check to See Whether it is the Default Browser. Click OK and, if and when you see a dialog box asking if you want Internet Explorer to be your default browser (probably the next time you open IE), click Yes.
