  1. Windows 10 Pro suddenly becomes not activated after upgrading to (10.0.17763.55)


    My Windows 10 Pro was upgraded from Win 8 Pro some years ago. It had been activated and signed into with a Microsoft account. I can see my Windows 10 Pro in the device list of my Microsoft account.


    Suddenly I found that my Windows is now not activated with error code: 0xC004C003. Activation Troubleshooting said "We found a Windows 10 Home digital license for this device running Windows 10 Pro." It happened after a few days I installed Windows Update for (10.0.17763.55)!


    Anyone knows what is wrong?

    :)

    Windows 10 Activation (Insider)

    I bought Windows 7 Pro OEM key from G2Play.net for 12€ to upgrade to Windows 10 Pro - worked like a charm but be advised if you buy a OEM key you can not download the Win 7 iso from microsoft and have to get it elsewhere.

    How long did you wait for activation?
    When I re-installed with a fresh install... it took a few hours to sync and activate.
    However, it did, finally, activate.

    Windows 10 Pro suddenly becomes not activated after upgrading to (10.0.17763.55)

    Windows 10 Activation (Insider)

    Hi!

    I signed up in the windows insider program and got windows 10 free - the windows 10 insider preview updated to windows 10 pro.
    Today i got another SSD and did a raid 0 on my system forcing me to do a clean install of windows but now it wont activate anymore.
    Signing in with my microsoft account that was linked to the insider program didnt help.
    Maybe i got this problem since i quit the insider program for several days and signed up again after i found out that my win 10 wont activate anymore.
    Any ideas how to fix it?
