Beginning with Windows XP Service Pack 2, Microsoft incorporated a Bluetooth stack into the operating system. The Windows Bluetooth stack allows the operating system to automatically install required drivers for managing attached Bluetooth devices. In addition to the Windows Bluetooth stack, other product manufacturers offer Bluetooth stacks for managing specific hardware. You may decide to uninstall the Windows Bluetooth stack to avoid conflicts with a Bluetooth stack from another company.
Select "Run" from the Windows Start menu. Type "sysdm.cpl" into the text box and click "OK."
