Microsoft Windows XP - Change The Default Applications Appearing In Your Start Menu (Win XP)
In Microsoft Windows XP, your favorite programs are displayed in the top-left column of the Start menu. By default, you'll begin with Microsoft Internet Explorer and Microsoft Outlook Express; however, you can easily have a different set of programs appear here.
To do so, simply right-click on an empty portion of the Start menu's left column and select Properties. Then, click the Customize button. At the bottom of the General property sheet, deselect the program you no longer want displayed (either Internet, E-mail, or both), and then click OK. Then, using Windows Explorer or My Computer, navigate to the program you want to appear on the Start menu instead. Right-click on the program and select Pin To Start Menu.
