Install win10 64-pro

hi.i install new win 10 64 pro on my chuwi 10air but i cant find driver for it & dont work screen toch.plz help about this.thanx

Always, I repeat, whenever a system reinstallation is going to be carried out, a copy of the drivers that are working correctly on the previous system must be made. I use the doubledriver app, freely available on the internet.
On the other hand, you did not have to have installed anything to go to Windows 10 Pro, just change the product key and everything would be fine in Windows 10 Pro since it only varies in that new functions are activated.
Since the damage is done, you must download the drivers from the firmware area and download your tablet model and install them manually on devices that are not recognized or fail
