Click on your Start menu and right click your My Computer
tab and click the option "Show on desktop" or something
like that. You can also cliick on any of the other icons
(Network Neighborhood, My Documents, etc) that you would
normally like to see on the desktop.
Press Start and right click on My Computer icon,
select "Show on Desktop". Do the same for My Network
Places and My Documents. Another way is to select an icon
and then hold down the Right mouse button and drag the
icon to the desktop (or quick launch bar, cleaner
appearance).
