I wanted a simple Windows 10 computer to capture dictation.  I have been using Windows PCs since the early 1990s, V3.1.  I wired it up, and turned it on, and the boot sequence started.  Except it wasn't a standard boot.  It has a security front end on it that wants you to allow it to track what you do, and send it to them.  They put a Windows 10 key tag on it, but it failed.  I tried all caps, lower case, spaces between groups of five, and no spaces.  Then, it just let me into Windows 10.  I poked around and it worked.  So I shut it down.  I turned it on and after the short normal BIOS, and a short display of something, gave me the background picture.  When I clicked on the picture it asked for my "pin" which I had entered during install. I accepted the pin, and gave me a black screen.  The only typing it accepted was crtl-alt-delete.  I selected task manager from that, and there were no tasks running.  ...then the black screen again. I am not happy.Product reconditioned by CNBcomputers, Inc, Mississauga, Ontario, Canada
