Does anyone know where one might be able to download an ISO file for Windows 8 Pro x64? I am not searching for Windows 8.1, which I know is readily attainable from Microsoft, but for the original release of Windows 8. I have a genuine retail product key for the Pro edition, but no ISO file to burn to DVD or write to USB flash drive from which I can install Windows 8.
Microsoft used to offer a Setup utility to download an ISO file or write the operating system to a USB flash drive, but the company pulled the link presumably after it terminated support for Windows 8. The Wayback Machine archived the utility and, while it runs, it is not functional, as it apparently cannot connect to the Internet to download the necessary files.
Please note that I am not looking for an ISO of the 90-day evaluation of the Enterprise edition.
Any assistance would be greatly appreciated.
