Windows Movie Maker - The best video editing tool for Windows that's absolutely free and chances are you already have it installed on your computer as part of XP SP2. Microsoft Movie Maker has all the basic video editing tools plus a good collection of transitions and video effects.
There's an in-built movie titler that lets add you styles to text titles including ticker taps, zoom and even the scroll effect. And if you are feeling lazy, just hit the AutoMovie command to have the entire video produced for you with intervention.
