This OptiPlex 7010 never had Windows 10 Pro installed on it before. I last tested this out on an OptiPlex 7010 with its Windows 7 Pro OEM key on the (>6 months after). Windows 7 OEM/Retail and Windows 8.1 OEM/Retail keys still act as Windows 10 OEM keys during clean installation resulting in normal product activation for systems that have never previously had Windows 10 installed. This misinformation was a marketing trick to entice as many users to upgrade as soon as possible. Microsoft's marketing campaign stating the Free Upgrade Promotional Window was Valid for only 1 Year i.e. This guide is Dell Based but equally applies to all other OEMs. For more details on the latest version see Windows OEM FAQs and Downloads. This guide was for Windows 10 Version 1607 which reaches End of Support in March 2018 and is superseded by newer versions.
Thanks in advance for leaving any donations Philip.
