can confirm the exact same behavior. I didn't have the guest additions
installed earlier on Windows 7 so the Windows Experience Index ran
correctly but gave graphics a 1. I installed guest additions in safe
mode with the experimental 3d support and then rebooted. Running the
test this time closed the VM just as you saw.

 I tested
again and found that if I disable 3D acceleration then Windows 7 does
not shut down when refreshing the index. It still shows a 1 though. So,
it seems that this patch might be surfacing something that is broken but
we didn't see until now. I had never seen anything official on 3D
acceleration actually working on FreeBSD so not sure if that even works.
