Some software isn’t glamorous or particularly mind-blowing; some just make your life that little bit easier. Windows Snipping tool is this type of software and what it does, it does really, really well.
Preinstalled on Windows 7 and free to download for Windows Vista, the snipping tool allows you to very quickly grab a still image from your screen. Excellent for highlighting eror messages for IT Support, for pasting images into PowerPoint or even WordPress blogs :),
The images can be sent directly to email, or saved, or annotated.
