Description
Prevents the user from enabling or disabling Active Desktop or changing the Active Desktop configuration. This is a comprehensive setting that locks down the configuration you establish by using other policies in this folder. This setting removes the Web tab from Display in Control Panel. As a result, users cannot enable or disable Active Desktop. If Active Desktop is already enabled, users cannot add, remove, or edit Web content or disable, lock, or synchronize Active Desktop components.
