Problem Capturing VLAN Tags With Wireshark

This has absolutely nothing to do with travel, except maybe in relation to frames traveling over a network, but I am desperate.

I have been attempting for days and days to capture VLAN tags using Wireshark. I have read everything I can find on this. None of it works.

The basic setup is a Cisco 2960 switch with this setup:

WS-C2960-24TT-L
12.2(44)SE6
C2960-LANBASE9-M

The computer is running Windows 7 Ultimate 64 bit. The Wireshark version is 1.6.5.

I have tried several different NICs. I am focusing on the Intel Pro/1000 GT as supposedly with a registry change it will show the VLAN tags. It does not.

Does anyone have a step by step set of instructions for doing this? I am tired of reading this and that and then trying to piece it all together on both the switch and the PC to make it work. I can see the traffic on VLAN 2 just fine using the gigabit trunk port. It just does not show the VLAN layer.
