Try: Control Panel>Add/Remove Programs--->Windows Components. Uncheck Windows Messenger. Reboot.
(That was how I got rid of mine.)
I just restored my Windows XP Pro and I now have 2 messengers? One is MSN Messenger which I use alot but as of today a messenger called ''Windows Messenger 4.7'' is now on my task bar next to my MSN Messenger 7.5? How do I get rid of the ''Windows Messenger 4.7''? Please help and all help is deeply appreciated. God Bless.
