It’s very simple to shutdown Windows from the command prompt. Here are some examples:

  1. To shutdown windows immediately, type:

    shutdown /s /t 0
  2. If you omit the /t option and type as below, windows will display a countdown of 30 seconds (default) before shutting down.

    shutdown /s
  3. You may also specify a different countdown value, for example: 60 seconds.

    shutdown /s /t 60
  4. For Windows 8 or later, you may choose to perform hybrid shutdown for faster startup on next boot.

    shutdown /s /hybrid /t 0
  5. To restart the computer, use the /r option instead.

    shutdown /r /t 0
  6. For a complete list of shutdown options, type:

    shutdown /?
