Does anyone know how to prevent MSN messenger from starting up on my PC? I have MSN Messenger 6.2 Everytime I boot up my PC, MSN Messenger is running in the background. I have "Run messenger during start up" unchecked everywhere I can think of. But I still have it running without me knowing it. I have to get into the Task Manager and end process. What gives? Why can't I turn it off and leave it off when I start up my PC? Edit. Ok, this is weird. I ended the task in Task Manager. But MSN messenger starts right back up again. WTF?
