I am confirming that IT DOES work with Windows Vista x86 SP1. And like Billy10 mentioned above, even though I edited the config file to have my actual IP address, which is 192.168.1.101, it kept trying to connect to 192.168.1.10 so I set my PC IP to that and it's working perfectly fine. I pretty much followed the DarkChild's instructions (big thanks), and the only Vista specific changes I had to do were run the WifiServer as admin, and that's about it. I see it responding within the GamePad CP, and I have tried a game with it, works perfect.
Cheers.
