uninstall MSN Messenger completely

Yes, I mean MSN Messenger. I have found the
special "code" to uninstall Windows Messenger, and I
uninstalled it. Then I installed MSN 6, but I noticed I
wasn't able to use the Remote Desktop or Whiteboard, and
possibly some other's unless Windows Messenger was
installed also. What's the point of this?! Most people
don't want two similar programs running

Now to my problem, I've uninstalled MSN 6 using the
control panel add/remove. Then downloaded Windows
messenger 4.7 and installed it. However, I noticed that
MSN messenger wasn't unistalled "completely". I noticed
that MSN Messenger was still listed in the sound schemes.
Is there any way to get this out of there?

Thanks for any help!!
