Last year we discussed “How to Capture a Screenshot as File in Windows 8?” which you will find useful in your desktop PC or laptop. You will also find that post useful in a Surface if you have a keyboard attached to it, because “Win + Print Screen” key combination is needed to capture the screen.
What about Microsoft Surface which does not have a keyboard attach to it? In that case, a touch keyboard will be require to press the keys but that will fill half of the screen.
