This Refurbished desktop computer was functional as delivered, but was not totally up-to-date.  The checklist that came with the unit boasted that the computer's drivers had all been updated, but that was not the case.  I was able to get the updated drivers from the Dell Website and that enabled Windows 10 to completely update to the latest "2004" version.  Without that, Windows 10 would not update beyond 1909 because of the Intel drivers.  My rating would have been a 5 as the computer has been perfectly operational since updating everything.
