The Snip It Tool is a small, useful piece of software that comes with Windows 7, Windows Vista and Windows 8. It allows you to very quickly capture screen shots (or 'snips') of a screen or a certain part of the screen.Once you capture a snip or a screen shot, the tool allows you to edit the image (you can scribble notes on it, for instance), share it, or just save it to your computer as is.
