Recommended way:
Create a Windows 10 installation pen-drive using Microsoft Media creation tool
Connect USB hub with pen-drive, keyboard and mouse to the tablet
Boot and press F7, select your pen-drive, install Windows from it
During installation delete all partitions and leave the internal flash empty, install Windows there
After that install drivers for the tablet from the package that you can download from this forum
This way you’ll end up with a clean Windows installed on a 64 GB partition
