I hope this thread helps others who were contemplating buying the upgrade license but haven't bought it yet because of the lack of clarity on whether a person can do a clean install using the license they'd buy for $39.99.

Well the simplest answer is yes you can. You can either do it by the registry workaround to change MediaBootInstall from 1 to 0 @ HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Setup/OOBE/

But the cleanest method that I have tried this weekend with success, is what I want to recommend to all fellow Neowin members.

Buy the license key using the upgrade advisor application.You don't need to download the ISO file. Download a legit ISO of Windows 8 Pro (MSDN/Technet) from your favorite torrent and install using the license key you just bought. Not only you will be able to install it but Windows will activate without any trouble.

I hope this makes frontpage so more and more people know they can do a clean install and how!

Yes, but how do you install on a clean hard disk, one that doesn't have any Windows installed?

You didn't mention that in your post, but yea the registry trick is the easiest and doesn't involve downloading from torrents and hoping your ISO is genuine / having to check the hash

Did it activate ok without hacking ?

That's because the other HDD that you didn't take out already had Windows on it.

I've explained that in multiple threads. It scans all hard drives in the system. ;)

@Shane - This is the information I've been searching for. My system has XP/64 and I want to install Win 8/64 Upgrade onto a new Hard Drive. So you're saying I can leave the old HD in there and just do the install onto the new HD. As long as the old HD is there to verify the old OS, the Win8 Upgrade will install. Then afterwords I can copy any data files from the old HD to the new C: drive and then reformat the old drive or remove it. Is all that correct.

Thanks,

Mike

      I and many others did not vote to get out of the E.u because of Putin or Farage, we did so for our own reasons. You don't have to tel me what my own did or did not do when it comes to the E.U. The EEC is or was the European Economic Community, a different beast to what the E.U is now.The EEC was a mainly about trading, the E.U have gone far beyond that and as I have said before, is now more of a United States of Europe. The U.K did not vote to join a United States of Europe. Anyway, they did not want us in there in the first place, Charles de Gaulle stopped us joining as he claimed we didn’t agree with the core ideas of integration. He was not wrong and that is why we voted out of the E.U when the time came. I was not old enough to vote the first time. My only regret is that we did not have the referendum years ago and got out years ago. If we rejoined, we would have to agree to join the Euro and no doubt Schengen, agree with freedom of movement, we have enough problem with people coming over here as it is. i have no problem with people coming over here if they work and don't try to push their way of life onto us. The E.U has a currency, freedom of movement, an anthem a flag, a parliament, well they are there, not sure if they do anything. Don't sound like something that is just for trading. Oh yeah, also wanted a euro Army. How many stupid rules have the E.U made that we had to follow? I doubt I will see the Uk rejoin the E.U, which suits me. Oh yeah, my partner is Polish, she came over here before Poland joined the E.U and she got fed up of people just coming over here with ease, while she had to struggle. She is now a British citizen and have been for a fair few years

      Hello, Paul. Thanks for the editorial. It was interesting. I'm going research more into the app and its concept. Of course, if you know me at all, you know that I'd say your articles needs some editing! I a;ways do, don't I? For instance, the article occasionally mentions a concept before defining it, e.g., relays.

    • U.S. partially reverses Anthropic AI ban for Mythos but keeps Fable 5 off the market

      By Karthik Mudaliar · Posted

      U.S. partially reverses Anthropic AI ban for Mythos but keeps Fable 5 off the market by Karthik Mudaliar Anthropic says that the U.S. government has finally allowed it to restore Claude Mythos 5. But of course, there's a catch. The rollout is again for a limited set of U.S. organizations that operate and defend critical infrastructure. The company announced this in a post on X (formerly Twitter). This does not mean that Anthropic's latest frontier models are back to normal availability. Fable 5, which was a tuned version of Mythos 5 for public release, remains unavailable. Anthropic said that it is still working with the government to expand Mythos 5 access and make Fable 5 available again, but there's no timeline. Reports from Bloomberg and Reuters say that this decision actually came through a letter from the U.S. Commerce Department. According to Reuters, this would allow more than 100 companies and institutions access to Mythos 5. Reuters also reported that Commerce Secretary Howard Lutnick’s letter removes the need for export licenses for approved companies’ non-US citizen employees, as well as Anthropic’s own non-US citizen employees, while restrictions remain for organizations outside the approved list. Anthropic isn't alone with this kind of controlled rollout. OpenAI's newest model family, GPT 5.6, was announced just yesterday, but isn't available for everyone yet. In its announcement, OpenAI also said that access to these models is initially limited to a select group of trusted partners and organizations, with broader access planned later this year. Both of these cases show that frontier AI launches are no longer just ordinary product releases and more like slow and vetted deployments shaped heavily by the U.S. government.
