Bluetooth is a wireless technology used primarily to replace serial cable connections by automatically connecting two associated devices when they are within close proximity of each other. The Microsoft Windows 7 operating system includes support for Bluetooth devices usually using drivers supplied by the Bluetooth device manufacturer. If a Bluetooth device that has been configured to associate with a Windows 7 computer fails to connect to the computer, restarting the Bluetooth stack can resolve the issue quickly in many cases.
