How do I take a picture with my built-in web-cam?

Possible duplicate: How can I take a picture with my webcam in Windows 7?

I've never used a web-cam before. I'm guessing that there is a some pre-installed program that allows me to take a picture or a small video.

I have a HP ProBook running Windows 7.

Edit: I no longer possess this computer, as it was my work laptop from my previous job. I appreciate the help of recent answerers, but I won't be upvoting or accepting answers, since I cannot verify them.
