A. Using policies it is possible to disable the display control panel applet, however it can also be accomplished using the registry editor

  1. Start the registry editor (regedit.exe)
  2. Move to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System
  3. From the Edit menu select New - DWORD value
  4. Enter a name of NoDispCPL and press enter
  5. Double click the new value and set to 1
  6. Close the registry editor

The change takes immediate effect and if you try and run the display control panel applet either by right clicking on the desktop and selecting properties or starting from the control panel applet you will receive the message

"Your system administrator disable the Display control panel"
