As I've said many many times, it's not a TB issue - it's an Intel issue. We can't fix their broken drivers. Older ones are "less broken" and instead of crashing they have slowdown problems, not ideal but still better than a crash.

As I've also stated many times they have made working ones for Windows 8, if you're lucky they'll fix the Win 7/Visa ones but it's unlikely. Old OS = no reason for Intel to support it anymore.
