Bluetooth Drivers
Bluetooth is a specification for radio-based wireless personal area networks. Bluetooth allows a way to connect and exchange information between devices such as PCs, printers, digital cameras, and mobile phones over a secure, unlicensed short-range radio frequency. One of the most common ways to see Bluetooth devices in action is witnessing a person walking down the street, talking, with a small device hooked on one ear, but without a cord leading to a cell phone.
Bluetooth drivers can cause problems for some devices, so software drivers may need to be downloaded and updated occasionally.
Older versions of Windows, prior to XP, require installing the Bluetooth adapter drivers yourself, and unfortunately, Microsoft does not support this. Windows XP with service pack 2 and later has native support for Bluetooth.
Microsoft's own Bluetooth dongle drivers (packaged with their Bluetooth devices) do not have external drivers, so you must have at least Windows XP SP 2 for those Bluetooth dongles to work correctly.
Vista Bluetooth drivers are in much better shape because Windows Vista has a built-in Bluetooth stack which is better than the Windows XP Bluetooth stack. I supports third-party driver development, allowing other companies to add support for additional Bluetooth Profiles.
