Did you install the chipset driver?

Yes i did. Still no luck

What shows in the device manager as having missing drivers (yellow splat)?

I googled on what is missing to enable touchscreen. It showed "HID Complaint touch screen" which should be under Device Manager. Which is not appearing

in device mangers click "view" and under view click "Hidden Devices" it will appear when you double click on HID 

The I2C hardware is your touch panel.

There are four chipset drivers you must install (rebooting as necessary in between):

THEN install the touchscreen driver.

Tried that too. Still no luck. I downgraded to Win8.1 to see if i can get some positive result. 

Please see the screenshot of my device manager..Device Manager

I am sorry for stretching this long... I installed all Device manager after installDrivers installed and updatedthe chipset drivers and I2C driver as well. Still no luck.. Is there anything else i need to do after this?

In device manager, expand Human Interface Devices. At the device manager taskbar, click Action, and then select Scan For Hardware Changes. Hopefully touchscreen driver appear. If the touchscreen still doesn't appears, click on View, and select Show Hidden Devices.
