you will require both a video recorder and editor...

some software have both in the same package, others are separate.

here is a free screen recorder
CamStudio is able to record all screen and audio activity on your computer and create industry-standard AVI video files and using its built-in SWF Producer can turn those AVIs into lean, mean, bandwidth-friendly Streaming Flash videos (SWFs)

I second Camstudio for freeware.

I highly recommend payware like Camtasia Studio, but if you must go free CamStudio is excellent.  I believe there is also a Microsoft option, but I don't recall the name.

I have been using Screencast-O-Matic for years
Thomas Zucker-ScharffSolution GuideCommented:
The last time I used screencast-o-matic I recall it having a time limit on each recording, is that still so?  What about Jing?

I have solo deluxe @ $16 per year, well worth the price
