I'm running Windows Vista Home Basic on a Compaq Presario laptop. (Well, it
was cheap.)

There are several programs I want to remove:

Online Services (Which expands to Easy Internet Services and a list of
online services in the US),

Windows Calendar, Windows Contacts, and Windows Mail (which I don't need
because I have Office Pro installed), and

Windows Photo Gallery.

They are not listed in Programs and Features or in Windows Features, but
they show up in the Start Menu.

HP told me I could just delete the exe files, but I find that difficult to
believe because just deleting them would leave the Registry unchanged.

Is there a way of removing these programs without messing up the Registry?
