I wonder if you were able to get the vlans working in windows7. I installed the driver and it shows under network adapters, but unfortunately the vlan never comes up, the main interface is up but the vlan always shows as cable unplugged or disabled. I use windows7 and the nic shows as realtek 8168rev3. My driver files are rt64win7.sys, rtnicprop64.dll. Vlan and priority are enabled. When i open the realtek utility and add the lan it creates the icon under the control panel network adapters but It does not really show in the utility itself. I wonder what could be causing the problem. Thank you.
found the problem. I was trying to run vlans between a virtualbox ubuntu guest system hosted in windows7 and a cisco sw. The problem is that the realtek vlan driver is not compatible with the virtualbox bridge driver. As soon as I disabled virtualbox driver from the nic, all vlans work correctly between the host OS windows7 64 and the cisco sw. Off course, once the driver is disabled I cannot use the virtual OS with vlans. bummer. I'll update if i find the way.
by the way there is a ticket open with virtualbox already ticket#7094
this link still works great and has been updated after 5 years from the original post.
