With the “Print Screen” button on your computer keyboard

  • Press PrtScn (or print screen). This copies the entire screen to the clipboard. You can paste the screenshot into any program that displays images, like Paint or Microsoft Word.
  • Press Alt + PrtScn. This copies the active window to the clipboard, which you can paste into another program. 
  • Press the Windows key + Shift + S. The screen will dim and the mouse pointer will change. You can drag to select a portion of the screen to capture. The screenshot will be copied to the clipboard, which you can paste into another program. (This shortcut only works if you have the latest version of Windows 10 installed, called the Windows 10 Creators Update.)
  • Press the Windows key + PrtScn. This saves the entire screen as an image file. You can find it in the “Pictures” folder, in a subfolder called “Screenshots.”

With the Snipping Tool on Windows 10

Microsoft includes a much more flexible screenshot utility with Windows 10, called Snipping Tool. You can use Snipping Tool to grab a screenshot and save it as an image file without first pasting the screenshot into another program. 

  1. Start the Snipping Tool from the Start menu.
  2. In the “Mode” drop down, choose the kind of screenshot shape you want — you can choose anything from full screen to rectangular to a free-form shape.
  3. Click New, and your screen will freeze. You can then use the mouse to create the screenshot. The screenshot will then appear in the Snipping Tool window.
  4. If you want to include something like a tooltip, which only appears after a mouse movement, you can specify how long to wait before taking the screenshot using the Delay menu.
  5. If you want to, once you’ve taken your screenshot, you can use the drawing tools to annotate the screenshot. 
  6. When you’re done, click “File” and then click “Save As” to save the completed screenshot to your computer.

You can also click the copy button in the Snipping Tool window — it looks like two pages laid over one another — to copy the image to your clipboard.
