we see:
· To downgrade eligible Windows software, end users must:
· Purchase a PC preinstalled with Windows software.
· Accept the Microsoft Software License Terms.
· Perform the downgrade process to the eligible downgrade product using the media/key from a genuine, previously licensed OEM or retail product.
One way of interpreting that that last bullet’s statement “…from a genuine, previously licensed OEM or retail product” would imply that a user with a PC that was purchased with a System Builder installation of Win10Pro, whose has already paid once for their Win10Pro OEM license, and who needs to regress to Win81Pro for some compatibility/whatever reason, must go out and buy another downstream Windows package (e.g. Win81Pro) somewhere (probably eBay), just so they have can have a Win81 product key to enter when installing Win81.
I don’t see any “downgrade right” financial benefit here whatsoever. The customer needs Win81 and had to go out and buy it somewhere at market price. So now the customer has paid once for the Win10Pro OEM System Builder license, and now has to pay once again for Win81Pro. If that’s the Win10Pro OEM System Builder Downgrade Rights benefit, then what’s the benefit of paying twice?
I look forward to any thoughts, comments or corrections.
