I have Sony Vaio Laptop with model number SVF15N15STS. The touch screen was working first times, but when I upgraded to Windows 10, it didn't work anymore, no reaction. I downgraded to windows 8.1 again, still no work.
Actually, I cannot find a good webpage of drivers for my model, I eventually found this page but it's so complicated.
I installed this driver, still not working.
I installed Pointing Driver (Synaptics), still not working. Also, I am not sure this driver is for my model.
I also tried to uninstall/enable/disable HID-compliant touch screen on device manager, still no work.
Btw, on device manager I have these (pics):
Any help will be appreciated!
