Try updating / roll back driver in Device Manager:
My Microsoft Tun Miniport Adapter #2 had a code 10 error and so i uninstalled it but now i can't figure out how to re-install it. my wi-fi doesn't work and i assumed that was the problem. anyway, at this point i would just like to re-install the adapter but cannot find the download anywhere.
what do i do?
