How to remove the Windows Messenger program from the computer?

1. Find and edit the sysoc.inf file (in the %systemroot%inf directory). In the "msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7" line delete the word "hide", and it will look like this: "msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,,7". Now you can uninstall the Windows Messenger in the common way: Control Panel - Add or Remove Programs - Add/Remove Windows Components – uncheck the checkbox for Windows Messenger (square icon). By unchecking the other checkbox you will remove the icon from the Start menu. 2. Go to Start: Ru.. and type RunDll32 advpack.dll,LaunchINFSection %windir%INFmsmsgs.inf,BLC.Remove (or copy and paste)
