  1. Windows 10 pro activation error 0xC004C003


    I bought my new laptop with Windows 10 Home this September. I bought an upgrade to Windows 10 pro on Microsoft Store and after installing new component I found that Windows are not activated with the error code 0xC004C003. Using troubleshoot was not helping, saying we can't activate continuously. There is no way to say that I'm offline. How can I fix it? Many thanks.
