Windows Ultimate pains

Downloaded a Windows ISO and find that it only installs Ultimate.

How to unlock all Windows 7 versions, a nod to my mate Chris for teaching me how to do this ;0)

Burn Windows.iso to USB (Windows7-USB-DVD-Download-Tool-Installer-en-US.exe) then open the usb and search for ei.cfg file in \sources directory and delete it.

This file sets Windows ISO to only offer Ultimate version, once it’s deleted you will be prompted for all Windows 7 versions during install.
