Not able to remove a program fully in Windows?

[OLIM2]

A computer with an administrator account and user
account, a particular internet access program works on
the Admin. but not the User account, so have tried to
delete and re-install on the administrator account, I
cannot properly remove this program, one part of it
removes from the windows add/remove list, but still shows
in the program files, but the other will not remove, says
is used by another program, is there a way of removing a
stubborn program from the Registry? If so, how do I find
the relevant program? I do know I have to save the
registry before deleting anything on it. The programs in
question are 'Yahoo Messenger' and 'Yahoo Mail',
downloaded and installed from one program. Yahoo Mail
seems to have installed itself into the Windows System
files! Could this cause a problem finding it in the
Registry? I want to do a clean install, in the hope it
will work this time. It had been working well, before
the Proxy settings on the LAN got deleted, were re-
installed and got onto the internet ok on the user
account, but then Yahoo Messenger not working!
Hope someone can help me on this. I'm sure I've read
somewhere that one can delete from the registry?
Await your response.
