How to take a screenshot on a computer
A screenshot, screen capture (or screen-cap), screen dump, screengrab is an image taken by the computer user to record the visible items displayed on the monitor.
In order to make screenshots you may use the special Print Screen button(PrtScr), which is usually placed in the upper-left corner of your keyboard.
How to use it:
On Windows, pressing PrtScr captures a screenshot of the entire desktop, while Alt+PrtScr captures only the active window.
Captured screenshots do not include the mouse pointer. Windows places these captured screenshots in the clipboard, meaning that an additional program needs to retrieve them from the clipboard.
Then the image can be extracted from the clipboard into the built-in Microsoft Paint software by pressing Ctrl+V on a new image.
Starting with Windows 8, however, Win+PrtScr instantly saves a screenshot to the "Screenshots" folder in "Pictures" library. All screenshots are saved as PNG files.
