The Microsoft Bluetooth Hands-Free Audio device is typically a Windows driver that enables Bluetooth headsets, speakers, or other audio devices to work with Windows PCs for hands-free communication. It supports the Hands-Free Profile (HFP) and Audio/Video Remote Control Profile (AVRCP) Bluetooth profiles, which are used for audio streaming, call control, and hands-free operation.

The device driver enables your PC to interact with Bluetooth devices, allowing you to use features such as voice calls, audio streaming, and media control directly through your Bluetooth headset or speaker.
