Prevent the "app settings" group from syncing to and from this PC. This turns off and disables the "app settings" group on the "sync your settings" page in PC settings. If you enable this policy setting, the "app settings" group will not be synced. Use the option "Allow users to turn app settings syncing on" so that syncing it turned off by default but not disabled. If you do not set or disable this setting, syncing of the "app settings" group is on by default and configurable by the user.
