My Solution
I just upgraded to Windows 10 from 8.1 with the same touch calibration problem.
All I did was delete the touch driver and then scan for hardware changes.
goto Device Manager >> Human Interface Devices >> KMFD HID Minidriver for Touch I2C Device
right click >> uninstall >> tick delete the driver software for this device >> ok
Action >> Scan for hardware changes
All done, touch working fine now.
