To make your computer look good and also to shorten the start menu, create a folder somewhere in your system and drag the shortcuts from the start menu and place it in the folder( say drag norton antivirus from start menu to a folder called security also similarly antispyware etc.,)
and remove all the programs listed in the start menu and removing all the shortcuts, drag this folder in to the start menu .. This would help you organise softwares on their contexts.
