Windows 10 offers several ways to take a screenshot. The fastest and easiest way is to use the Print Screen key on your keyboard. To do this, simply press the Print Screen key (sometimes labeled as Prt Scr) and then paste the screenshot into an image editing program like Paint or Photoshop.

If you want to take a screenshot of just one window, you can use the Alt+Print Screen shortcut. This will take a screenshot of the active window only and copy it to the clipboard. You can then paste it into an image editor to crop and save it.
