The command prompt is the command-line interface in Windows. When using the command prompt, you control the computer by entering text commands (instead of clicking on icons with your mouse). In some cases, support will ask you to use the command prompt because it is the most efficient way to get the necessary information.

To open the command prompt:

  1. Go to Start > Run (or hold Windows button + R on your keyboard).
  2. Type cmd and click OK (or hit Enter on your keyboard).
  3. A black box will open with white text at the top.
  4. Enter the commands that support asked you to run and press the Enter key. When you are finished with the command prompt, you can type exit and press Enter to close it or click the red cross.
