I set up the computer and attached the monitor to it.  I began the Windows installation process......in French.  I don't speak French.  I started over, chose United States English, the U. S. keyboard layout, etc.  It flashed an error message, reverted me back to French, and would not accept English or Spanish.  I gave up and accepted French.  It then would not accept today's date and would go no further.  I was finally able to install a purchased copy of Windows 10 Pro from my Microsoft account.  Also, the keyboard had at least 1 non-functioning key, the "L" key, which I needed to enter my email address.  Fortunately, I still had an old spare keyboard that worked.  I am not a very happy customer, nor am I the least bit impressed with Microsoft support.  Their customer service number refers you to their website, and that was no help at all.  Speaking to an actual human being might have solved at least the software issue.  Good luck actually speaking to one directly.  I guess Bill Gates had to cut some costs so he could upgrade the 66,000 square foot house he lives in.  Shame on Microsoft.  Shoddy and disgusting.
