How to capture VLAN tagged packets

I want to capture packets with VLAN tags (from a Cisco switchport in trunk mode), but not having any success on my Windows 10 machine. I've followed the Intel guide to enable the passing of the tags but still no luck. When I connect to the same port and run Wireshark on an OSX 2009 Macbook Pro, it works fine.

Have tried both an Intel Pro 1000 MT and 82579LM NIC. Each requiring the different registry value, due to their driver type.

Any help appreciated.
