No matter what version of Windows you're running, there is a simple and universal method for taking screenshots: simply press the PrtScn key on the keyboard.
PrtScn:A single click of the button records a screenshot of the whole screen. A single click of the print screen button will help you to save a screenshot of every linked screen if you have many monitors connected.
Alt+ Prtscn:To take a screenshot of just the window you're concentrating on, press Alt and PrtScn simultaneously. Press these keys after selecting the window once to ensure that it is focused.
