The restore-point safeguard creates a Windows recovery point before Bluetooth Driver Installer changes driver configuration. The utility then tries to apply a generic Microsoft Bluetooth driver so Windows can recognize an adapter that is not configured correctly.
What does the driver installer change?
The utility applies a generic Microsoft driver by modifying Windows' Bluetooth configuration file, bth.inf. This targets adapters that Windows has not set up properly, including both USB Bluetooth dongles and built-in hardware. It is intended to bring the adapter under the Microsoft Bluetooth stack so Windows can handle basic Bluetooth connections.
This approach depends on the adapter working with Microsoft's driver. Hardware that needs a manufacturer-specific driver may not be detected or may lack device-specific functions after the change.
How does it protect existing Windows settings?
Before making system changes, Bluetooth Driver Installer creates a restore point. Windows System Restore can then be used to roll back the changes if the new driver setup causes trouble.
- The wizard checks for Bluetooth hardware that is not configured.
- If it cannot find unconfigured hardware, exiting at that step leaves the system unchanged.
When should you use the Microsoft Bluetooth stack?
This tool fits driver problems such as an adapter that Windows no longer recognizes or a Bluetooth stack that prevents devices from connecting. After the adapter is working, Windows features such as pairing and file transfer may be available, depending on the hardware and its driver support.
The software addresses driver setup; it does not diagnose every possible cause of a connection failure. If the adapter is unsupported by the generic driver, its manufacturer’s driver may still be needed.
Pros
- Creates a restore point before changing Bluetooth configuration
- Works with USB dongles and built-in Bluetooth adapters
- Can restore access to Windows' Microsoft Bluetooth stack
Cons
- The generic driver does not work with every Bluetooth adapter
System requirements: 32-bit and 64-bit
Does Bluetooth Driver Installer provide drivers for every adapter?
No. It applies a generic Microsoft driver that works with many, but not all, Bluetooth adapters.
Can the changes be undone?
Yes. The utility creates a restore point before changing the system, which can be used with Windows System Restore.
What happens if no unconfigured Bluetooth hardware is found?
The wizard can be exited at that step without making changes to the system.
