Instead of waiting for Intel to fix it's drivers/software, I thought I would try something different.
I installed Apple's OSX Mavericks on the NUC, and it works vastly better than Windows with Intel software. I spent less time installing/configuring OSX than I did trying various things to get Windows 7/Intel software "working". In fact, I had no Mac knowledge and embarked on this option with less headache than dealing with workarounds from Intel. Instructions can be found by searching for "tonymac x86 intel nuc".
A wholly unsupported operating system with hacked drivers works better than the officially supported stuff.
