Hi. I have an ASUS X550C laptop of which mobo has a built-in product key for Windows 8(.x), non-Pro. I found recently that with a "multiple-edition" DVD of Windows 10 the non-Pro edition would be installed automatically probably using the built-in Win8 key even when trying a clean installation. So I would like someone tell me how to edit this DVD. I have a 10 Pro key purchased. Thanx.
