I Call Dell.com USA . They say I would have to contact the previous onwer to reregister the computer in my name if I wanted any Dell Support.  When I gave them the model number s/n number. They Laughed because Dell hasn't been able to update any drivers for Windows 10 operating system on a desktop that old.  It's my fault for not buying a newer one  $$ . And also for not shipping it back to the seller.
