Windows Hot Keys
Print Screen: Pressing the Print Screen (or sometimes labeled PrtSc) key takes a screenshot of your entire display and copies it to your clipboard. This function is fairly useless unless you have another program to paste it into, so the natively available Paint program frequently accepts such shots for cropping, annotating and saving. One advantage of this method is the ability to capture pop-up menus, such as the right-click context menu, by opening the menu before snapping the shot.
Windows-Print Screen: Holding the Windows key and pressing the Print Screen key takes the same entire-desktop screenshot, but it automatically saves the result to the Pictures library, which you can find using File Explorer. This is perhaps the quickest option for taking a desktop screenshot for emailing or archiving. Like the previous method, this hot key can also capture pop-up menus.
Windows-Alt-Print Screen: Pressing the Windows, Alt and Print Screen keys simultaneously restricts the screenshot to the active window, so if the image you wish to copy resides in a single program, you don’t need to capture the extra fluff. Unlike the previous two hot keys, this one won’t capture pop-up menus, because the act of pressing the Alt button removes the menu before taking the shot.
