If the system does not support the install-on-demand of extension servers, UnregisterExtensionInfo removes all extension servers in the Extension table associated with either an uninstalled feature or a feature installed as advertised from the registry. Otherwise, this action removes the extension servers associated with a feature that is selected to be removed from the registry.
