Windows Movie Maker is the main tool for amatuar movie editors. It's free, and straight to the point (from what I've been told). I've never used it though.

Fraps is a commercial screen-recording program. Very, very simple to use. However, the demo records only 60 seconds at a time and the full version costs about $20.

I didn't pay for mine though..!
