Fixed it. This laptop model runs ALPS drivers. I was installing synaptics drivers back then and they didn't seem to work. When i installed ALPS drivers of windows 7 on this laptop, the problem is fixed.
No gestures features work. The movement is painfully slow. No support from Sony on windows 10. There last touchpad update was for Windows 8.1.
Laptop model: VPCEH18FG
Searched everywhere but can't find a solution. Really frustrated.
