How to screenshot part of the screen under windows?

I would like to use mouse to select a part of a window under Windows and then take screenshot and save it as jpeg format. Is there such a functionality provided by Windows or some applications? I asked on behalf of a friend, as I am using Ubuntu exclusively and the built-in screen-shot in Ubuntu allows using mouse to select part of screen. Not sure which Windows edition he has, maybe Windows 7 or XP. Thanks!


Solution 1:

If they are on Vista or Win7, there is a new Snipping Tool that does exactly what you describe included. Just type "Snipping Tool" in the start menu search bar and it will open up.

Available in:
Snipping Tool is available only in the Home Premium, Professional, Ultimate, and Enterprise editions of Windows Vista/7.

** I just ran across this little gem which adds a snipping tool for XP users. http://xpsnipping.codeplex.com/
