I have a Touch Pro 2 with US Cellular. I downloaded the link from EGOvoruhk above:
HTC Wi-Fi Sharing.cab and installed it. I went to Start and the WIFI was there. I tried it the first time and my PC did not detect the network from my phone. I stopped it and started it again and my PC found it and connected perfectly. No registry hacks. No hassles. Thanx EGOvoruhk.
