Request for Chuwi Hi 12 x5 Z8300 windows 10 latest update with drivers

I have a Chuwi Hi12 SN Q64G45160100668 Model CWI520,
around six years ago.I installed only windows. Now my windows are not working smoothly,many times it crashes.So I want to reinstall Os,will you please provide the windows version with all drivers and the steps to do this?I tried a lot of times to correct it but nothing happened.So this request is my last way to return my tablet back.I will expect a favourable help from your side.
