Vista - Default Applications on Main Start Menu, How can I remove them?

I have another issue however I am not sure where to post it. On the
start menu, you have default applications and files, however every time I
click "Remove From this List" on the default programs and files, they come
back after I log off then back onto the user account. Why won't they stay
removed? I.E. I want to
remove AOL and Windows Media Player from the main Start Menu. So I click
"Remove From this List" and it goes away, but after I log off and then back
on again,
they come back. I can't get rid of them. What is the problem here? It
does this on every user profile on three new computers with Vista Business.
Even the ones that have adminstrator privileges.

Regards,
