Yesterday, I spent a good 10+ minutes looking for a driver, the HT BT450 Bluetooth Adapter driver. I Google’ed, then I Yahoo!’ed, then I went straight to HP’s support website… always using the keywords: hp bt450 bluetooth xp driver. I either got nowhere or found the Vista version, here. That was until I found this page… and the direct link to the driver, here. I hope this helps someone else, because 10+ minutes of “searching” is way too long especially for a driver! -Thuan
