Installing just Windows is pretty easy. You would need to use a mouse and keyboard attached to an USB hub.
I think the best way to do this is to do a complete clean/delete of the ssd drive in order to remove the Android disk partitions Windows install doesn’t see. I used Acronis Disk Backup software but I also think Clonezilla has a similar feature. There are probably other programs as well. You have to be able to boot from the software using an usb stick attached to the hub because you will be deleting all the contents on the drive. Once the drive is “clean” you just have to install Windows as you normally would.
Be aware that if you have a pirated version of Windows, which appears to be the case with these tablets, you will loose your Windows activation.
What issues in Android are you referring to? My dual boot is running very well – though I dont used the 3G – I prefer to tether to my LTE phone.
