Working with the Microsoft Bluetooth Stack

I was looking for a way to use the Windows Sockets Bluetooth API: http://msdn.microsoft.com/en-us/library/aa362932(VS.85).aspx

I quickly learned that if you can compile and build an example, it will likely not work on your Windows machine, because it will have some other Bluetooth driver stack installed, as opposed to the Microsoft stack. In order to quickly diagnose and resolve that issue (and basically replace the other stack with the Microsoft stack), check out this most excellent tool:

Of course, you should only do this on a development machine where you are not afraid to muck around with the drivers and potentially mess something up. However, it worked great for me and all the comments I found about the tool were very positive, so my personal confidence in it is high.
