One way is to simply uninstall the application in Add/Remove programs. That usually does it.
These apps are alos often in the C:\Documents and Settings\All Users\Start Menu\Programs\Startup folder or C:\Documents and Settings\%userName%\Start Menu\Programs\Startup folder. You can delete teh entry there if uninsatlling does not work.
Some applications will be uninstlled from the program folder. So Start Programs Progam Name "uninstall program name"
Some require a regitry change which would require more info on teh exact application.
