They do make it hard, don't they? Good for you d0pestar knows just how to remove Windows Messenger from Windows XP once and for all:
1) Go to Start > Run
2) Type this exact commando (you might want to copy paste):
RunDll32 advpack.dll,LaunchINFSection %windir%INFmsmsgs.inf,BLC.Remove
3) Oh my God, you killed Windows Messenger! ;)
If for some reason this doesn't work for you, try this:
1) Open a file named sysoc.inf with Notepad or another text editor. This file can be found in a folder named INF, which is a subfolder of the Windows folder (or in some cases the winnt folder, depending on how your OS was installed).
2) Look for the following line:
msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7
and remove the word "hide" while leaving the commas on place. Close and save the file.
3) Now open the Add/Remove Programs applet in the Control Panel, and you will be able to remove Windows Messenger like any other program.
