One of my favourite features (I’m easily pleased) of Windows Vista is the Snipping Tool. Fed up with the old print-screen/MS Paint/crop method of getting screen/window grabs and not wanting to use a 3rd party graphics application, I was happy to see that Microsoft introduced their Snipping Tool into Vista. It had previously only been available as a add-on for tablet PCs. You can find it under Accessories in Vista.
It seemlessly allows the creation of Window, Free-Form, rectangular or entire screen grabs that can be annotated and highlighted. It works with multiple monitors and remote desktop sessions and eases the creation of documentation or showing someone something. After all, a picture is supposed to speak a thousand words.
