Some people do not want to use MSN Messenger for chatting and would like to remove it from their computers. With Windows XP, this is not always so easy.

Another Way is,

Find  the file named sysoc.inf 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). 
Usually it should be located in the C:\windows\inf\

Edit the file with notepad.

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.

Now open Control panel / Add or Remove Programs (for both of the above methods). Then choose Click on Add/Remove Windows Components. Search for Windows Messenger & UnInstall it. You can now remove both services. They have a bug with the check boxes but it still works.
