I don't remember whether I've ever tested this with SP2 and don't
remember the exact SP3 behavior changes either. Anyway, I did see
something change with either XP SP3 or Vista ;-).

It should be a completely separate IE that is after the WPS IE (nice
that both of them are called WPS).. I'm not too surprised if sniffers
don't recognize the Microsoft Provisioning IE, though.

I'm not familiar with this type of issue in Intel Proset, but that could
indeed be something similar. It seems to be easy to do something bad in
auto-detection code and WPS is a good way of triggering these issues
