Disabling Windows Hot Keys

You can completely disable Windows hot keys Ctrl+Alt+Delete and Windows+L. After disabling the hot keys, nothing happens when the hot keys are pressed.

Disabling Ctrl+Alt+Delete

1. You must first disable "Windows secure logon", so that you do not need to press Ctrl+Alt+Delete from the windows login screen. Use one of the following procedures.

2. While signed in as an Administrator, open the command line and run the following command:

reg add "HKLM\SYSTEM\CurrentControlSet\Control\Keyboard Layout" /v "Scancode Map" /t REG_BINARY /d 0000000000000000030000004de01de04be01d0000000000 /f

3. Log out of the system and log in again. To re-enable Ctrl+Alt+Delete, run the following command line.

reg delete "HKLM\SYSTEM\CurrentControlSet\Control\Keyboard Layout" /v "Scancode Map" /f

Disabling Windows+L

Run the following command line.

reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "DisableLockWorkstation" /t REG_DWORD /d 1 /f

To re-enable Windows+L, run the following command line.

reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "DisableLockWorkstation" /t REG_DWORD /d 0 /f
