Can't Upgrade to PRO / Can't Get Past "Product Key" Window
Hi,
I am trying to upgrade GENUINE Windows 8.1 PRO x64 to Windows 10 Pro x64 from the ISO I made from the Microsoft RTM files. I am upgrading from within the 8.1 OS and choosing the option to keep "nothing" of my settings and personal files.
I have two problems.
The first is that the installation asks for a product key. On the other hand, when I upgraded my Windows 7 machine to 10 from within the OS it didn't ask for a product key. Why do I need to provide the product key to upgrade my 8.1 system, but not my 7 system?
Second problem is that I can not upgrade from 8.1 PRO to Win10 PRO. When I put in the general product key for the Win10 HOME edition the install proceeds, but it does not take the other (different) product key corresponding to the Win10 PRO version, even though it should. Why can't I go 8.1 PRO -> 10 PRO?
Thanks lots for any tips!
