disable controlpanel

Question

i have used following code to disable the Windows Control Panel. It successfully disables the Control Panel, but it needs a sytem restart to apply changes. Does anybody know how I can apply these changes to the Control Panel immediately, without requiring a system restart? Can anybody can help me?

        RegistryKey RegKey = Registry.CurrentUser.CreateSubKey(@"Software\Microsoft\Windows\CurrentVersion\Policies\Explorer");
        RegKey.SetValue("NoControlPanel", true, RegistryValueKind.DWord); RegKey.Close();

        RegKey = Registry.LocalMachine.CreateSubKey(@"Software\Microsoft\Windows\CurrentVersion\Policies\Explorer");
        RegKey.SetValue("NoControlPanel", true, RegistryValueKind.DWord); RegKey.Close();

        //registry
        RegKey = Registry.CurrentUser.CreateSubKey(@"Software\Microsoft\Windows\CurrentVersion\
        Group Policy Objects\LocalUser\Software\Microsoft\Windows\CurrentVersion\Policies\System");
        RegKey.SetValue("DisableRegistryTools", true, RegistryValueKind.DWord); RegKey.Close();

        RegKey = Registry.CurrentUser.CreateSubKey(@"Software\Microsoft\Windows\CurrentVersion\Policies\System");
        RegKey.SetValue("DisableRegistryTools", true, RegistryValueKind.DWord); RegKey.Close();
        return true;

You could try to run Gpupdate after you made the registry changes. This should in theory reload the group policy details and therefore disable the control panel.
