I will be updating this review for buyers. Initial setup: product key supplied is not being accepted by Microsoft for Windows 10. Quick start sheet suggests contacting Microsoft for issues. I did. Microsoft's key requirements do not match what was supplied by cnbcomputers (Microsoft wants 6 or 7 digit blocks of key numbers while this comes with fiv digits). CNB states its hours of technical support begin at 9am EST. They do not answer their phone and the outgoing message states they are closed and to go to the website (cnbcom.com#support), which, of course, is under maintenance. Therefore, no technical support assistance. UPDATE: Without the assistance of tech support, which never replied, I was able to activate Windows: Bypass product key requests and get to the desktop: start, settings, update & security, activation. Enter the refurbished key code here (without dashes). It worked for me. Will update this review with overall product review in the future.
