    Windows 10 will not activate after upgrade / clean install?


    Hey Guys

    I upgraded from 8.1 (genuine Sony Vaio ) using the media creation upgrade option, it installed and activated to windows 10 pro.

    I then used the same media creation tool to download the iso and used Rufus to put it onto a usb so that I could do a clean install.

    I installed it and skipped the parts prompting for a product key, however once it loads up when I try to activate it states 0xC004C003 details section says the key has been blocked?

    Have I missed something?

    Any help appreciated.....thanks.

    Activation server is dealing with some stuff. I have the same error, windows support told me to try again in 24-48 hours after they verified my product key would work.

    No. I just think their activation servers are very busy. I had the same problem. After many activation attempts, it finally went through.

    Thanks for the info guys.... When I click on the activate windows link again, it doesn't go through the checking stage ie round whirling icon, it just brings up the same page,stating windows is not activated.
    Are you all getting the same?

    I upgrades two machines using the Download Windows Tool rather than Windows Update. One activated almost straight away, the other wouldn't activate at all. Called MS to try and get some help and when I was describing the problem to the agent it activated.

    Looks like it is just stress on the activation servers.

    Yes, just give it time. I couldn't activate for a number of hours yesterday and was wondering if there was a problem with the upgrade but when I turned the PC back on later it showed it had activated.
