Hi Majid nazari,
Thank you for reaching Microsoft Community. I'm sorry to hear about what happened to the touch functionality of your Surface Pro 4.
In the Device Manager under Human Interface Devices, is the Intel Precise Touch driver listed? Try also clicking on View on top then select Show hidden devices and see if HID compliant touchscreen driver shows up.
How about other drivers, are there any other drivers that is getting a error especially under Firmware? If yes, kindly provide us with the Device name of the driver and it error code.
Kind regards,
Marrion
