Hi Guys, Not sure if this is a question that can be answered here but here goes. I want to install Windows 10 in Parallels. Because Windows 10 is an upgrade normally one would download the media creation tool. Whilst going through this creation to media Windows looks for your windows 8.1 serial or 7 if you have that. If one is installing Windows 10 from an ISO file it can't have the connection to your old Windows and associate the serial with that. How do I get around this? Do I install my Windows 8.1 serial?
