I have a gateway laptop (stats are in profile) that I tried to stop some of the items on the startup menu. I received a warning that I was changing the way windows starts and did I want to continue. One of the items was the windows messenger. Is there a way to tell what start up items are necessary and which are not. I had checked the items here I am a little nervous about changing the setting that came programmed into the computer. Thank you for your help ahead of time.
