Actually, printing the screen in Windows 10 is something very simple.
Most keyboards today come with a screen print key (Print Screen) if the keyboard is in English. If the keyboard is in English the key will be Print Screen ( PrtScn ) . The key is usually at the top next to the F12 key.
Pressing the Windows key will take a screenshot and save it to the clipboard in a place in your memory. Then it's time to open an image editor. For example, the "Paint" is useful. Once in the editor menu, we select paste. So when the clipboard capture is pasted into the open Paint file, we'll have to save the file.
Another more practical option is to press the WINDOWS + Print Screen key and automatically save the image to OneDrive > Pictures > Screenshots. This way is much more comfortable.
