Windows 7: Live Messenger Start up problem.

I have Windows 7 Pro x64 and my wife uses Live Messenger for video chatting with her family.
I keep un-checking the box for Messenger in the msconfig/startup box.
But every time my wife manually starts Messenger, msconfig gives birth to a new check box and Messenger starts up at boot again.
How can I just use Messenger when we want to without it going live in msconfig anymore?
Thanks.

Hiya pal

open live messenger...go to the tools tab, click it, and go down to
"options", and when it opens select the "general tab", then "uncheck" where
it says " automatically run windows live messenger when i log onto windows.
click apply, then ok.

Or with pictures:

Thanks guys.
I'll see how it works.
