Removing Programs In Windows Xp

Hi! How do I remove those programs that gets installed automatically with Windows XP, such as Windows Messenger and Movie Maker? I can't find their entries in the Add/Remove menu (only programs installed after have entries there). Windows Components menu doesn't have their entries either. Can someone help?

Thanks
