Edited: What I wrote below is no longer true. It was just a issue with one of pre-Windows 10 releases. It should work fine in retail version. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Windows 10 is no longer backwards compatible with NDIS 5 and current Winpcap release at winpcap.org is design for NDIS 5. You can get fork of Winpcap that able to work with NDIS 6 at http://www.win10pcap.org/download/Win10Pcap-v10.1-5001.msi At least technical preview have this problem as Windows 10 did not release yet, but I will guess since it removed in technical preview it probably not going to be in real release ether.
