Greetings Len,

To fully remove Windows Messenger 4.x, close down Messenger if it's running (right click the
messenger icon in the notification area/system tray and click close).  Then click the start
button, then click Run and type in (copy-paste if you like):

RunDll32 advpack.dll,LaunchINFSection %windir%\INF\msmsgs.inf,BLC.Remove

Then click OK.
Messenger will then be uninstalled.  For more detailed instructions and screenshots, go to,
