Snipping Tool captures a screen shot of anything on your desktop, like a picture or a section of webpage. Snip a whole window, a rectangular section of the screen, or draw a freehand outline with your mouse. Then you can annotate, save, or e-mail the image using buttons right in the Snipping Tool window.
