sharing windows pc internet via usb option to oplus xonphone 5

During process of sharing windows pc internet via usb option I am not able to select pc system version as there is no option to show? I am using oplus xonphone 5 with android 4.4.2 os.

After using other option i.e. usb tethering my pc shows other unidentified network with internet access but still I am not able to access internet on my mobile.

please help. my phone is not rooted.
