    Lost activation after Win10 update Nov build 10586 [Error: 0xC004C003]


    Guys, need some feedbacks on my problem I'm facing right now on my WINDOWS 10 PRO:

    - I joined Insider program in Nov,'14 to get a taste of developemental version's upcoming features of Windows 10 Tech Preview.

    - My Tech preview got updated on 29th Jul,'15 during first worldwide release of Windows 10 public release!!

    - In Sept,'15 , (I was running my PC as dual boot ie, Ubuntu 10.14 & Win 10 Tech preview both). As I got the Full public version of Win 10 Pro so I tried to remove the Linux OS. But, during removing Linux OS I encountered "disc.img missing" with bluescreen issue. I had to completely format my PC with brand new partitions. I then did clean install of the WIN 10 PRO taking the Disk image from the Microsoft website.

    - To activate my newly installed Win 10 Pro, I contacted Windows Answer Desk & after a dozen of logical Q&A the person activated my PC via remote access.

    - On yesterday (7th Dec,'15) after auto updation of my PC with the Nov build 10586, I again lost the activation. I was hoping post updation after restarting the PC & connecting the internet my new build windows will get activated intelligently!! But, sadly it didn't.

    - I tried manually entering the product code (which I noted down & saved when the Windows executive guy was activating my PC via remote access). Still no luck !! [Error code: 0xC004C003]

    - Twice, I did chats with the Answer Desk & they were simply chanting the same line "You need to purchase the new key to activate your windows"

    - Interestingly, they said no logs are available of my previous contacts to Answer Desk for activation!! Even no logs are present for me in the Answer Desk person I named!! Ohh one more thing, on the release code I mentioned they said it was "abused" ie, used on multiple devices!! So, now that code is blocked!! Interestingly, they said this for their own uniquely generated product key...woww!! How can that be possible when all windows activations go through windows online servers only at present??

    - After couple of hours of exhausting useless chit-chats with the Answer Desk, with little hope I just rolled back my PC to the earlier build & saved my PC from Deactivation!!!!!!!!

    Now, need your views guys, what was this all responses from Microsoft suggests ? Now, should I avoid updating my Windows 10 from now on Or any other precautionary steps I should take to prevent from such kind of deactivation issue!!

    Thank you!!

    As an Insider, assuming the upgrade was from an activated 10240 build with a logged in Insider MSA, then you should be OK - but ask in the Insider forum... I dropped out a long time ago.

    The key and subsequent (blocked key) error code is irrelevant on such activations.

    @Superfly :

    Is there a way to tell if rparashar89 has a digital entitlement activation vs. a product key activation on build 10240?

    @rparashar89:

    From and elevated command prompt ("run as administrator" command prompt), run: slmgr /dlv

    Please post the results. You won't need to black any information out, there is nothing unique in the display that can be used for piracy.

    Yes WDT will tell if it is...

    ...however not being activated makes little difference.... I can't get any activation info from digital entitlement from the installed system (it's either encrypted or hidden in ClipSVC events) - everything seems to be on MS servers... so WDT wont help either, sadly.

    But he does have an activated Windows PRO installed from a backup image now - it's just when he upgrades to 1511 he loses activation.

    Yup, the previous activation is of no consequence to the current - what we need to 'diagnose' is the current loss of activation - that is not that easy.

    If he has a digital entitlement then it would seem like an inability to activate in the future would be because a wrong version is attempting to activate and the correct version should activate with no product key.

    WDT is still in development (as per the GUI)...also as per the posts here.

    The old version is available at EF:
    Please Read: Activation troubleshooting.

    Insider activation is flaky... I think with the convergence to GA their activation routines got messed up, but that's an opinion... theoreticaly an Insider should update from any new Insider edition and retain activation.
