By default, Windows Live Messenger starts when Windows does. If you don’t use it on a frequent basis, you are wasting resources by having it run when you don’t need it.
1. Open Windows Live Messenger and login.
2. Next to your name, at the top, click the downward pointing arrow.
3. Select Options.
4. Select General from the left pane of the Options window.
5. Under Sign In, uncheck the Automatically run Windows Live Messenger when I log on to Windows checkbox.
6. Click OK.
