    Brand new Windows 10 product key showing "Already used" 0xC004C008 Error on brand new built PC


    Hello! I am a new system user who has just built my first PC.I purchased a Windows 10 Home license from Microsoft brand new, and used the USB stick to install windows to my fresh system. Install went fine, I was able to change my personalization options briefly. But after a restart, Windows asked for the activation key and is returning the "0xC004C008" error that says it's activated on another computer. This is a brand new system and a brand new key. I don't understand how it could be activated on another computer. My Microsoft account only shows one system: the one it's installed on right now
