Go to Startup and look for something called Help and Support with a (?) icon. Mines in french so im not sure what's writen in english. Well when you find it click on it.

Well that help thing keeps poping up when i start windows XP pro... how can i turn it off?

Type msconfig in the Run dialog box when it opens click the start-up tab and go through the list looking for help and support centre I'm not sure exactly what it will be called but when you find it remove the tick and that should prevent it from starting up. Same goes for anything else you don't want starting up.
