The Bluetooth service supports discovery and association of remote Bluetooth devices. Default: Manual. Counter Measure: The recommended state for this setting is Disabled. Potential Impact: Already installed Bluetooth devices may fail to operate properly and new devices may be prevented from being discovered or associated. If Bluetooth devices were installed, then some Windows components, such as Devices and Printers, may fail to operate correctly - including hanging/freezing when opened. The solution, besides re-enabling this service, is to disable or delete the offending Bluetooth device(s) in Device Manager, or disable the device altogether via the system BIOS (if it is an on-board Bluetooth device). Fix: (1) GPO: Computer Configuration\Windows Settings\Security Settings\System Services\Bluetooth Support Service (2) REG: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\bthserv!Start
