Windows Home is pretty much standard, I remember seeing some people get windows pro on the really early releases of their iwork8 tablets back in maybe 2015 but they were rare AFAIK
Thanks for replying.
Pro has some advantages, especially regarding some settings for Windows updates, but for daily use Home is fine.
I was more interested though in if and why Cube possibly would install different Windows versions on the same type of tablet. Therefore this topic.
