What operating system?
Vista? XP?
If in Xp, then go to Control panel (START > CONTROL PANEL) and click on "ADD/REMOVE"
In that menu you will see a whole list of installed applications.
Click the ones you want to remove and press "CHANGE/REMOVE"
This will launch the uninstaller for you.
Vista is simular, but the "ADD REMOVE" menu is now called "PROGRAMS" and is still located in control panel.
