The website for the computer I received read...."MICROSOFT AUTHORIZED REFURBISHED - Microsoft Authorized Refurbishers (MAR) are recognized as the leaders in refurbished computers for every environment. Following strict requirements and standards established by Microsoft, MAR providers ensure superior quality and a like-new professionally refurbished computer. Your computer will come with a legal Certificate of Authenticity (C.O.A.) digitally rendered to the PC for an easy, secure and convenient set-up process."Don't know who wrote this but it wasn't apparently communicated to Sunset Micro. I've purchasedMicrosoft Authorized Refurbished Computers before. Never disappointed The computer received from Sunset Micro looked like it was taken from under a desk... after many years... and stuck in a box that was laying round... a label stuck on... and out the door.Amazon has a vendor relation problem with Sunrise Micro that needs their immediate attention.
