[Hi12] [Official Version][Dualboot] Chuwi Hi12 Android, Remix, Windows, Bios, driver

Hi,
the initial post has some broken links and I think it is now obsolete.

What are the correct files to reinstall Windows (including drives if needed) and Android on my Hi12?
If possible I would also like to have the relevant guides.

My product serial number is Q64G45171000914.

@Management can you help me?

P.S.: Maybe I also need the bios, I would like to try this guide:
[TUTORIAL] How to remove Android and install Windows on a dualboot tablet (Intel Processors)
and if something goes wrong maybe I need it to reactivate all the functions?
