Hello, I got a herobox pro with windows 10, but once I installed windows 11 the key disappeared, I tried some solutions online but none of them worked, its error code 0xC004C003. It shows up in settings but it doesn’t show up when I looked for it in cmd. How can I fix it? I don’t need to revert to win 10 then reactivate it then reinstall win 11 do I?
Hello, please try to restore win10, thank you
This worked on my CHUWI HeroBook AIR of two months old.
