If you're running Windows XP or NT, you've probably received messages while you're on the Internet, advertising some product or maybe even wanting you to buy software just so that you won't receive any more messages. These are from the Messenger service, a service not related to MSN Messenger, and you don't have to pay for software to disable them. With one click, this program will permanently turn this service off, unless you decide to turn it back on. Note: your Windows account must have Admin privelages in order for this program to work.
