Hello I got an iWork Air yesterday and today I did to it the same procedure as my Teclast tablet. Booted with a pen-drive with Windows 10 64 bits (32 bits seems that it is not supported) versión 1607. Erased all partitions and installed Windows. Then downloaded and uncompressed the drivers from this web to the pen-drive and installed drivers for all devices marked as unknown in device manager. After connecting it to my WiFi, Windows got activated and started installing updates. For me it has worked exactly like the other chinese Windows tablets that have passed through my hands. In a tablet with only 32 GB of storage I prefer to use it all for Windows.
You also deleted the recovery partition? i want to do this to my iwork8 air too, but i don’t know if i have to delete the recovery partition, thanks.
