Make Sure you Run the Application Under Administrator Rights

if you have made registry changes in HKEY_LOCAL_Machine else it will work without administrator rights if you Disabled

TaskManager From HKEY_CURRENT_USER :)

please check "Do you like this answer" if helps you :)

private void btnEnableTaskManager_Click(object sender, EventArgs e)
        {
            RegistryKey rkey = Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Policies\System\", true);
            rkey.DeleteValue("DisableTaskMgr", true);
            rkey.Close();

       try
         {

            RegistryKey rkey2 = Registry.LocalMachine.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Policies\System", true);
            rkey.DeleteValue("DisableTaskMgr", true);
            rkey2.Close();
         }
         catch
         {
          }

            MessageBox.Show("Regitry Enabled !!");

        }
