How do I remove Windows Messenger from Windows XP?
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.
