    failed activation Windows 10 Build 10240


    Well I removed the 10240 because it's worthless to me with no way to activate it. I installed a copy of Win 8.1 that I had laying around and I believe I'll wait until after the release to upgrade it. So now I'm dual booting 7 and 8.1.

    I was able to activate a clean install of 10240 a few hours ago. Not sure if it's still working !

    Do an upgrade install from 8.1 and it should activate. It's only clean installs that are blocked, or were blocked?

    For some weird luck I've manage to activate my system using this steps

    ** Illegal KMS REMOVED **

    things that bothers me is

    is this legal?
    will it stay activated forever?
    will it stay activate if i do clean install again

    Anyway guys thank you so much for your response.

    failed activation Windows 10 Build 10240

    I tried to install 10240 on my Dell Venue 8 Pro, which had legal Windows 8.1 (home) on it. I did a clean install via iso, resulted in that Windows 10 wasnt activated, and also denied activation. Tried several keys wild on the web.

    Then I re-installed Windows 8.1, activated it, run the setup from the iso from inside activated Windows 8.1, did a clean upgrade... resulted again, after boot, Windows 10 wasnt activated and couldnt be activated anymore.

    Then I found this post and tried, and it worked... but now so many more questions are there. Why!? Is it legal? Will it stay activated?

    I think the problem was, that the Venue 8 Pro just has a Home edition of Windows 8.1, and not a Pro. And the wild isos of 10240 all are just Pro, I couldnt find any Home edition iso at all.

    But why did this trick work, with this key? I tried before another workaround posted on reddit:

    ** Illegal KMS REMOVED **

    And the above did not work!

    I dont really know what I should think now of this...

    I was, and the tablet, an insider before btw several months ago. But I switched back to Windows 8.1 during the past months. This didnt seem to help anything at all, because people sayd the machines ID should have been flaged/saved on MS servers.
