I have a Sony VAIO VGN-FE11S, that came pre-installed with Windows XP Media Center Edition 2005. Currently I have Windows 7 Ultimate 32-bit installed on it and seems to work pretty well, apart from some programs like IE and, to a less extent, WMP forgetting their settings. My question is: how can I install the Bluetooth drivers without Bluetooth Stack for Windows by Toshiba? The reason why I don't want that app is because of being a 30-day trial and Windows built-in apps are enough and work pretty well anyway. BTW, Device Manager shows me that the Microsoft Bluetooth Enumerator and Sony Bluetooth USB Adapter are properly installed and updated. Still, they aren't the manufacturer's drivers. Any suggestion?
