Download free Bluetooth Driver Installer for Windows 8
Get Bluetooth to work with the Microsoft Bluetooth stack. This small freeware utility will try to install generic Microsoft driver for your bluetooth adapter. It works for most (but not all) bluetooth adapters, both USB dongles and built-in. Before making changes to your system the program automatically creates a restore point. If anything goes wrong you can use Windows System Restore feature to revert all changes made to your computer.
