Disable Icons in Control Panel - Digerati - 2003-12-18
Use this Registry setting to disable the Display icon in Control Panel, as well as the Properties option when a user right-clicks on the desktop. By disabling these options, you will stop the user from changing settings that control monitor resolution as well as screen saver and wallpaper options. To disable this option for a user, open the Registry Editor and go to:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
Policies\System
Edit the value "NoDispCPL" (DWORD value) and set the value equal to "1"(without quotes) to disable the Display icon (if the value/key does not already exist, create it). To re-enable the option, delete the above value or set the value to "0". The setting will take effect immediately
and does not require a reboot.
