My Vista Notebook works fine with this (Just got it to work actually). Only problem I noticed was that the ad-hoc connection wasn't connecting by itself on my notebook. I had to go in and manually add an ad-hoc connection in the wizard. I named it "WMWifiRouter" just like it says on the screen. Once I did that, I hit connect on the laptop (it says it's waiting for connections or some such). then went to my i760 -> Settings -> COnnections ->Wifi -> select WMWifiRouter (after the WMWifiRouter software is already running) and hit connect at the bottom left. Yeah, it's a pain, but it connected and worked great. And FWIW, I am using the trial as well.
