It is very easy to take a screen capture for free.
Step one. Once what you want to take a screen capture of is on the screen hit the print screen key on your keyboard. This will transfer the screen capture into memory. (Note that holding alt and striking print screen will take a capture of the active window only.)

Step two. Open a graphics editor such as paint and press paste to put the image into the graphics editor. (Paint is located in start/programs/accessories.)

That's it! Its that easy to take a screen capture totally for free using the feature built into Windows.
