Yes, in Windows 10 it is a little bit trickier to identify NDISWANIP interface and yes, you are right I have to update ListAdapters sample.
However, it is not a complex task at all. in order to do this you have to enumerate subkeys of the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\{4D36E972-E325-11CE-BFC1-08002BE10318}. Each subkey represents a network interface and the name of the subkey is the same as returned by WinpkFilter driver internal network interface name. For each network connection subkey you have to open ‘Connection’ subkey and check ‘PnPInstanceId’ value. If it is ‘SWD\MSRRAS\MS_NDISWANIP’ then this connection corresponds NDISWANIP connection under earlier versions of Windows.
Hope it helps…
