Launcher Restarter is an utility which restarts Headwind MDM launcher after crash or update. It is required on some Android builds like EMUI (where launcher is not restarted after updating).
I recommend always include Launcher Restarter in the configuration.
You do not need to show the icon of Launcher Restarter because it is useless. To hide the icon, open the configuration details, open the Applications tab, find com.hmdm.emuilauncherrestarter (or Update Helper), select Icon: Hide, then save the configuration.
