I found the solution to my problem.
You go to
Control Panel -> System and Security -> System
and on the right there is the link of the
Click that and then when the Device manager shows up you.On the top of the Device Manager windows there is a button which says
you click that and there is an option which says :
Show hidden devices
Then you have to find the Network adapters section and click the arrow which is placed on the beginning next to the Network adapters.When you click the arrow all the network adapters will show up including the ones which are hidden.You find the one which you want to delete and you press the right click.After that a small menu will pop up and it will give you the option to
the network adapter you have right-clicked on.
