One option that works great on Windows is using the Print Screen (PrtScn) key. The PrtScn button can take a screenshot and save it as a file and can also take a screenshot of only one window. This button is usually labelled as PrtScn, PrtnScrn or, Prting Scr. On some keyboards, usually laptops, the Print Screen button may need to be triggered by holding the Function key and then pressing PrtScn. When you press the button to take the screenshot nothing will actually happen on the screen, but the screenshot will have been saved to your computes clipboard.
