You can add a Turn off display command to the Windows 11 desktop right-click menu by importing a registry file that creates a shell-menu entry. It sends Windows a request to turn off the display; it does not shut down or put the PC to sleep. The registry recipe comes from a third-party tutorial, so inspect the file before running it and use the tutorial’s matching add and removal instructions.
What the context-menu command does
The command adds an item to the desktop context menu—not a general File Explorer menu command. When selected, it requests that Windows turn off the display. Microsoft documents the underlying WM_SYSCOMMAND message as 0x0112 and SC_MONITORPOWER as 0xF170; an lParam value of 2 requests that the display be shut off. This is distinct from putting Windows to sleep or shutting down the computer. The API values describe the request, not a guarantee that every PC, driver, foreground application, or display connection will respond identically. Microsoft Learn documents the message and its parameters.

Add the desktop menu item
ElevenForum provides registry-file instructions for creating the Turn off display desktop menu item. Follow one complete version of that tutorial rather than mixing its registry data with command-line fragments from other posts. The tutorial is third-party guidance, and community reports on the page include older Windows 11 builds, so compatibility with every current build is not established. See the ElevenForum add and remove instructions.

- Inspect the registry file’s contents before importing it. Confirm that it creates the intended
TurnOffDisplayentry and that its command matches the tutorial version you are following. - Import the inspected file using the tutorial’s instructions, then right-click an empty area of the desktop and choose Show more options if needed to see the classic menu.
- Select Turn off display. This sends a display-off request; it does not select sleep or shutdown.
Remove the menu item
The tutorial’s removal recipe deletes the TurnOffDisplay subkey at HKEY_CLASSES_ROOTDesktopBackgroundShellTurnOffDisplay. Use the tutorial’s corresponding removal file only after inspecting its contents. Alternatively, remove that specific subkey in Registry Editor if you are comfortable editing the registry; avoid deleting neighboring shell entries. The tutorial includes the removal instructions.

Choose a selected monitor instead
The context-menu request is not a per-monitor targeting control. If you need to select a particular display, NirSoft’s MultiMonitorTool provides command-line controls for monitors. NirSoft notes that its monitor on/off operation requires DDC/CI support, so it is a separate utility-based approach rather than a property of the Windows context-menu verb. NirSoft MultiMonitorTool details.
| Approach | Scope | Dependency | Important limit |
|---|---|---|---|
| Desktop context-menu verb | Requests display shutoff; it does not select one monitor. | Registry entry and Windows display command. | Observed behavior can vary by hardware, driver, foreground activity, and display connection. |
| MultiMonitorTool | Can address a selected display. | Optional downloaded utility. | NirSoft says monitor on/off control requires DDC/CI support. |
If the desktop context menu is missing
If shortcut menus are missing throughout the desktop or File Explorer on a managed PC, an administrator policy is one possible cause—not proof that the policy is configured on your computer. Microsoft documents NoViewContextMenu as a policy that removes shortcut menus from the desktop and File Explorer. Ask your organization’s administrator before changing managed settings. Microsoft Learn lists the policy reference.
