Answer 1

How Windows Messenger functions on your computer

In their initial state, Microsoft Windows operating systems (98, ME, XP, 2000, NT) allow anyone on the Internet to actuate pop-up messages on your screen. Here is an example of a pop-up generated using Windows Messenger:

Pop-up generated by Windows Messenger Service

The sender need not know anything specific about your computer in order to generate the message, and Windows Messenger makes no attempt to evaluate the validity of the sender or the message. Malevolent individuals can generate pop-ups that try to fool you into taking actions contrary to your best interest; and spammers use Windows Messenger as a method for distributing their advertisements.

So far, it appears that Windows Messenger pop-ups all have "Messenger Service" in the window title (see illustration). If you receive any such message that instructs you to take actions that may divulge sensitive information, change your password, visit a web site, or take other potentially hazardous actions, you should consult with a computing support staff person before proceeding. You should also check before choosing to disable Windows Messenger - or any other Windows service - to make certain you don't inadvertently turn off a service that your department uses.
Disabling the Messenger Service

To prevent anyone on the Internet from generating pop-up messages on your computer, you can disable the Messenger service. You can restart the service easily at a later time if you decide to use it.

Answer 2

If your talking about windows messager that comes with windows and auto runs everytime you start your computer. Go to the control panel then to add/remove programs. Depending on what windows version you have. Along the left side of the window should be Add/Remove windows programs or something along those lines. Now look for the windows messager or "MSN" messager (they are the same for those of you who didn't know) and uncheck it then click apply. That should do it.
