There are any number of 3rd party screen grab utilities but here are some integral ways of doing so. Snap, Snap, Grin, Grin…
ToW #183 uncovered a hack to replace the WindowsKey+S combination OneNote used but which was appropriated by Windows 8.1 preview, meaning that Win+S snappers were left with no easy way of capturing areas of the screen.
GREAT NEWS! The RTM of Windows 8.1 (or is it an update to OneNote?) has restored the ability to capture areas of the screen, this time by using WindowsKey + SHIFT + S. This method has the benefit of being able to screen grab parts of the Start screen and of modern apps too.
Windows 8.x devices
To quickly add the whole screen (or a combination of all of your displays if you’re running multi-mon) to the clipboard, just press WindowsKey + PrtScn.
If you want to capture the whole screen and find yourself lacking a PrtScn button (eg on the Surface) or in fact with no keyboard at all (eg tablets aplenty), you are able to grab the screen(s) by holding the volume down button and pressing the hardware Windows logo, at the bottom of the screen. The screen dims momentarily in both of the above methods, to let you know that the image has been dropped into the clipboard, ready for pasting into Word, Outlook or your favourite image manipulation app. Or MSPAINT.
Windows Phone 8
Simple – lightly press & hold the power/standby button and quickly press the Windows button on the front of the phone. The screen flashes briefly, the camera shutter noise may play (so careful playing with this feature in any situation where you wouldn’t want to look like you’re taking a photo…) and the resulting image is saved to the Screenshots folder within the Pictures hub.
