I'm sorry that in your zeal to find fault and nit-pick you completely overlook and misinterpret every salient fact in the article, and how those directly apply to the OP's original question.
By the the way; we would all be eternally grateful if you would post the link to the "legit Windows 8 isos right from Microsoft at no cost", and also explain in detail how the upgrade reg hack is not in direct violation of the Microsoft EULA.

I don't intend to argue, but i'll at least answer your questions.
Legit Windows 8 ISOs right from Microsoft? If you know anyone with an MSDN/Technet/Dreamspark/MSAA subscription you can get them there. You can run this tool from Microsoft (
http://go.microsoft.com/fwlink/?LinkID=262204) to download the files and choose "Install by creating Media," if you'd prefer. There's an open access folder on Digital River with Windows 7 and Vista media as well, i'm unsure if they've added Win8 to it though. If you want more you can google them.
As for the registry hack? It's absolutely not against the EULA, as long as you
own the original license that qualifies you for an upgrade. I never suggested that you buy an upgrade license and use the hack in lieu of purchasing legal licensing, and neither did the guy in that link. That guy merely claimed that it
cannot be done, and offered convoluted and expensive alternatives, which is not only false but misleading to the reader. I've had Microsoft customer support reps do this very registry hack for me when I had mislabeled media and the key wouldn't activate during installation. You obviously need to meet the licensing requirements to use upgrade media, and a clean install is in no way against the EULA. Hell, if you're upgrading from XP to 7 or 8 a clean install is the *only* option. Nowhere in the EULA does it state that if your hard drive dies and you need to reinstall, you have to reinstall the previous OS first and go through the upgrade procedure. You merely need to still be in possession of the previous OS license for it to be a legitimate and legal install.
So no, that guy does not address the OPs comments or concerns, he did not detail activation/deactivation triggers, a considerable amount of his technical information is misleading and/or incorrect, and he sacrificed any credibility of what was supposed to be a technical article by thickly seeding it with his own personal bias and misinformation.
I don't like Windows 8 either, but that guy is still wrong.
