There are some times you just need to record everything that is happening in your desktop. You may need a short video for your class presentation, a tutorial or for business demonstrations. Here's a great alternative from all the expensive commercial software which allows you to capture your desktop with ease. CamStudio lets you record all your desktop activity and export it into AVI or into SWF. Once you start using it and will have to do a software presentation, you won't have to demo everything right on site - you will play it back from CamStudio.
