After you install XP, you'll notice that some of the icons from previous versions of Windows is gone, like Network Neighborhood and My Computer. If you would like these back, right-click on the Desktop and select 'Properties' then click on the 'Desktop' tab. Click on the 'Customize Desktop' button and then on the 'General' tab. Check the items you want. This screen also has the 'Clean Desktop Now' button, which notifies you of unused icons on the Desktop and offers to remove them for you.
