Quickest way to take screenshot in Windows 8

Taking Screen shots (Snapshot of the active screen) in Windows 7 was considered tedious wherin you had to paste it in a picture editor like MS Paint and save it to your desired location 

In Windows 8 this has been made easy with a shortcut key combination .
Just press and hold the windows key on your keyboard and press PrintScreen Key 
This will take the snapshot of the active screen and save it as a png file in documents folder .
No need to use any other application for saving .
