Where is Thunderbolt in Windows 7 on MBA2012?

Am I the only one not seeing Thunderbolt in the MBA2012 device manager?

Anandtech posted where to find Thunderbolt in Device Manager for the MBA2011, but I haven't been able to find an image verifying where/how it shows up in MBA2012 yet.

So should I just delete the installation and reinstall Windows 7 before I get in too deep (installing more programs) and hope that Thunderbolt sticks the second time around? I thought Thunderbolt was there initially because I connected the Gigabit-to-Thunderbolt adapter for all my Windows update downloads two weeks ago before shelving the MBA2012 while I waited for the Zagg Invisibleshield to arrive, but since revisiting the installation and trying to connect the MBA2011 in Target Disk mode, I see no sign of Thunderbolt in Windows. (Thunderbolt is working in Lion.) I have one new important update to install, maybe that'll do the trick....

So I reformatted and reinstalled and Thunderbolt is back.

This time I used the ISO suggested here:

But who knows how long it will last...

And it's gone again!!!! Why?!?!
