You probably already know that pressing the PrtScn button in Windows copies the entire contents of the screen to the clipboard. To work with the captured image, you then can use MS Paint or a similar application to edit, crop, and save the picture.
There’s a faster, better way to take screen shots in Windows Vista. It allows you to outline the segments of the screen with the mouse pointer that you wish to copy, and then save the image in a variety of formats without having to start an image editing tool.
It’s called the “Snipping Tool.”
To enable it, click the Vista start icon and type “snipping tool” into the “Start Search” field. Vista will then pop up a dialog asking you if you would “like to add the Snipping Tool to your QuickLaunch bar.” Click yes, and then the snipping tool will appear. Note that it may not appear immediately in the QuickLaunch area. (You may need to click the double-chevron icon to find it in the pop-up list.)
