Just to clarify, Windows Messenger is part of the standard XP installation and does not appear in the add/remove programs list. MSN Messenger is not a standard component, does appear in the add/remove programs list, and is most likely what she downloaded/installed as it has more features than Windows Messenger. I'm pretty certain that your entry called only 'MSN' will be MSN Messenger, although it's always appeared as MSN Messenger on my add/remove programs list, so I'm unsure as to why it wouldn't on yours.
MSN Messenger can be deleted with no problems at all. Windows Messenger holds various .Net/Passport and user account information for other programs/.Net/Passport applications which require a login and this may be why it's not so obviously removable.
My best advice would be to remove MSN messenger. Then, if Windows messeger still signs in with her details, simply go to Start > Control Panel > User Accounts > Adminstrator(or whatever your primary user account with administrative rights is called, or the account she logged on and created the MSN account within if there's more than one XP user account) > Manage My Network Passwords. Then, highlight and remove any stored user names and/or passwords which she may have created for either MSN or Windows Messenger. That done, you should be back to a clean, messenger account-free setup.
