A easy, but not great way would be to just press the print screen button on your keyboard.

Or, you can open the video in Windows Movie maker, get to the time you want to take the image from, click on Tools, and click on Take Picture, and save it. (Not sure how good this works, haven't tried it myself, i just know of it)
