hi in the end i download the windows files from the Teclast site, and installed only the windows, with their guide and it worked great!
But this tab has many problems , after windows annual update i cant use the touch screen. double tap just not working, no matter what i tried.
also cant use micros sd slot, cant read the card =\, i wonted to buy the Teclast x3 pro, but after this tab ,i reconsidered..
