[QUOTE=philamber;2753881]It seems as though Microsoft is going to make users, even beta testers, pay for the upgrade.[/QUOTE]
Since MS has said they’ll allow qualifying users to upgrade from 7 & 8.1 for free, the question is if the 10 beta testers have to roll back to 7 or 8.1 (as previously installed on the computer, assuming they don’t have the 10 beta installed on a separate partition), or if those beta testers will be able to use their 7 or 8.1 key during installation without having to fully roll back.
If it’s the former, it shouldn’t be difficult for some users to install 7 or 8.1 to a small partition, get their upgrade, then overwrite the Win10 beta once they get their upgrade key (assuming they’re sticking with activation keys). Annoying, yes, but not too difficult.
