Advised by seller to download recovery media to reinstall Windows 11 when Windows wouldn't activate.  Also, unit was advertised to have 512 SSD hard drive, but unit shipped with two 256GB hard drives.  This seller takes factory units and upgrades them and reboxes them before selling.  I am on a deadline and do not have time to reinstall Windows, or return for a unit as advertised.  Will be looking for another seller.
