    So, I think I'm in the same boat. I had a legit version of Windows 7 for a long time. Was using Windows 10 with the Insider Program. Installed the final release of Windows 10 with the media creation tool using the "Upgrade" option first. Everything looked good and it showed activated. I wanted a clean install, so I ran that and now it won't activate.

    I don't have my old Windows 7 key to even attempt reinstalling and I stupidly deleted the Windows.old directory (actually had two of them... one for Win7 and one for Win10 beta I think) because I thought it was successfully activated, so I can't restore that or recover my key from it.

    Am I pretty much screwed at this point?

    Same problem with me. Unable to activate Win 10. Code 0xC004C003. I upgraded from Win 7 (regular licence) to Win 10 on 6 August by clicking on the Windows icon displayed on the tools bar. Microsoft Customer Service in France told me to wait. But I don't understand why it takes so long time and why there is no official communication from Microsoft about this topic.

    Please make sure that you clean installed the same version (Home or Pro) that you originally upgraded to.

    Hey guys I have an update for you. I was having problems with my clean install activating as well even after I made sure that the upgrade activated. So I went back to Windows 7 and then I restarted the whole process and now its working. In both stages, upgrade and clean install, it was already activated when I checked it. It has been a couple of days since I've done it and it has not been revoked or any thing.

    Heres what I did, I'm not sure if anything I did here made a difference but the end result was good:

    1. Rolled back to Windows 7, in my case I had cloned my permanent drive to a temporary one before starting the upgrade process.

    2. Checked for and removed device from Microsoft account. When I checked my Microsoft account the computer showed up twice, I removed them both.

    3. Upgrade to Windows 10:
    Before doing this I uninstalled my antivirus.
    I upgraded by using USB installation media that I created using the Media Creation Tool. I launched the Setup application from file explorer.
    During the upgrade process I choose to NOT to do updates, NOT keep anything and did not link my Microsoft account(stayed with local).
    When the upgrade was done, I checked activation and it had already activated.

    4. Clean install Windows 10: I
    I started my clean install 30secs after seeing the upgrade had activated, have seen some posts saying to wait a couple days even at this stage to insure clean install activates.
    I started clean install by booting from the same USB installation media I used to upgrade.
    During install I choose to clear all existing partitions and again NOT do updates or link my Microsoft account.
    When clean install was done, I checked activation and it had already activated, then I linked my Microsoft account.

    If you selected to not keep anything, then you just did a clean install. There is no reason to do another one.

    I made some similar, i rolled back to a backup of win 8.1 pro, then I used the USB to upgrade, I followed the tutorial on the forum, and I choose the option nothing(clean install on upgrade), I used to download the updates while installing following the tutorial; I skipped the MSA and made a local user, when the operation was done the license was already activated without logging on the MSA.(i have a backup of this)

    anyway I did a clean install(format and partition wipe) with the same USB following the same procedure, but sadly it didn't work out.
    I was logged on MSA during the win8.1>win10 that because of the store needed to install the 8.1 update.

    I will try again to clean install without the lan cable.

    the installation asked me 3 times to skip the key, did you got so many requests?


    edit: ok Im rolling back to win 8.1 and try the sme stuff without upgrades.

    Not exactly, when choosing to keep nothing it leaves two partitions on the drive from Windows 7 that are useless, making the total 4 partions because Win 10 makes its own recovery/reserved partition. Sure I could have just repartitioned the drive after the update, but I like starting from a clean slate.

    Yes, I forgot to mention all the key requests I had to skip.
