Persistent Windows activation notice

I received my Chuwi Herobox a little while ago and i am very pleased with it. recently a notice to activate windows has appeared in the bottom right of my monitor. I know i windows was activated as soon as i started using it, it was the first thing i did. I contacted Microsoft to query this and they stated that my windows is in fact activated. the notice to activate windows is still there and i cannot resolve it. can you help.
