I want to go get a TechNet subscription to test some Windows software before I buy it. I want to replicate upgrading Windows 7 to Windows 8 with specific software in a virtual machine then see how stable or if possible to do it at all. I looked at the list of software but they only show Windows 8 Pro or Enterprise. Do you know if there is an Windows 7 to 8 Upgrade ISO available for Technet Standard or Pro?
