I moved to Windows 10 by using the free upgrade from Windows 7. I am currently on Parallels 15. I want to perform a clean install of Windows 10 but how do I do that since I don't have a serial number for Windows 10. Thanks, Jim
When you downloaded the free up grade from windows 7 you received a digital license from Microsoft. In Windows 10, the digital license associates itself with your device's hardware. I am not sure this will work but have you tried to install windows 10 using the option of skipping entering the license key? I sent you a Private message.
