This vendor, Skytech USA, LLC turned out to be a real Microsoft Authorized Refurbisher.  This vendor has an affilitate called AST who did the actual refurbishing and provides the tech support.  Everything was first class and professionally done.  It came in a box customized to the computer and sealed in tape saying Microsoft Authorized Refurbisher.  The computer was sealed in shrink wrap, with printed instructions and it has a Microsoft holographic Windows sticker on it.  This computer was listed as a "Prime" item.  It also came with a new keyboard and mouse.  After connecting a cable to my router, I booted it up and it ran a Windows 10 startup program perfectly.  I answered a few questions and it installed and activated Windows 10 without a problem.  It shows in Windows 10 as activated with a digital license.I say all of this because I returned another so called Amazon refurbished computer last week that was a disaster from start to finish.  It took weeks to ship, was bubble wrapped in a generic box, contained photo copied instructions, no Windows holographic sticker, no keyboard or mouse and last but not least it could not find a hard drive attached when I turned it on.  I returned it via the Amazon returns process and I am awaiting the refund.  So buyer beware with Amazon refurbished computers.  I would only buy another Amazon refurbished computer if it was also listed as a PRIME item.  I think Amazon makes sure all PRIME items meet a better standard.
