I've run sfc and DISM a number of times now and have rebooted also but sfc is still finding errors that it cannot repair. Just checked and Windows Update is showing never checked and never updated. I'm not going to obsess or worry about it though since the system appears to be operating normally with no issues yet. I imagine that MS hasn't finished populating the driver database and probably some other stuff as well. Still have a long time till the final release date.
