Since the modern era of Windows began with Windows 95, taking screen shots with Windows meant you had to press the screen print key, then open up MS Paint or a 3rd-party application and paste in your screen shot.
Windows 8 has finally stepped up and made this a much simpler process. If you press the Windows Key + Print Screen (or Windows Key + Volume Down on a tablet computer) Windows will grab the screen shot and automatically save it in your Pictures folder as a PNG file. While it’s not nearly as feature-full as something like FastStone Capture, it’s great for capturing a simple screen shot in a hurry.
That’s great news, however is there anyway of saving the pics as a JPEG rather than a PNG?
