Hey mate, did you managed to get it to work? If not, there is a post with the drivers in this forum.
I have thought to do the same as you, changing to win 8.1 as i believe i would have way less problems.
Everytime my win10 updates there is a new problem to be solved. Right now im trying to solve 3 problems that the updates created on me:
– No sound;
– No signal on SD Card slot;
– Touch screen acting annoying.
About the touch, i managed to reinstall the old driver (KMDF HID Minidriver for Touch I2C Device) and it now knows where im touching but the problem is that it right clicks each touch i make so im trying to fix that.
Best regards
