I downloaded and burned to DVD Win10 ... I did a clean install onto another partition which went fairly well.... But I ran into a few problems I hope someone can help with... 1.) Windows 10 is asking for the product key. 2.) I noticed the version of Win10 installed was the wrong version. I have Windows 8/8.1 Pro with media center, but Windows 10 Home was installed. My questions are where do I get the product key from? MS never sent one or supplied one when I downloaded Win10. My Windows 8 key does not work for Win10. And why would the Home Edition be installed when I have Win8 Pro installed?
