Windows Movie Maker 2 is much easier then the first version adn its A lot better then the first one....it still pretty basic.

Check the microsoft site and you can dl sound effects, title and exit videos and other goodies for it....

also by going to the tools menu you can create title screens, credits and on video text and add transitions. its actually pretty self explanitory and its something you can figure out by playing around with it for about 10 minutes...
