The steps to create a shutdown icon on the desktop screen may vary depending on the operating system you are using. Here are the steps for Windows 10:

    1. Right-click on an empty space on the desktop screen.

    3. Select "New" from the drop-down menu.

    5. Click on "Shortcut".

    7. In the "Type the location of the item" field, type "shutdown.exe /s /t 0" (without quotes) for an immediate shutdown or "shutdown.exe /s" (without quotes) for a timed shutdown.
    8. Click on "Next".
    9. Enter a name for the shortcut, such as "Shutdown".
    10. Click on "Finish".
    11. The shortcut icon should now appear on your desktop.

You can also customize the icon by right-clicking on it, selecting "Properties", clicking on "Change Icon", and choosing an icon from the list.
