Microsoft Bluetooth Enumerator Driver

The Microsoft Bluetooth Enumerator is a Windows system component that identifies Bluetooth devices and makes their services available to the operating system. Its driver works alongside your Bluetooth adapter’s driver to help Windows recognize connected accessories, such as keyboards, mice, and headsets. On Windows 11, 10, 8, and 7, this Microsoft component is normally supplied with Windows rather than installed as a separate hardware driver.

Key Features

• Bluetooth device enumeration: Creates device entries for detected Bluetooth services so Windows can load the appropriate supporting drivers.
• Accessory support: Helps connect Bluetooth peripherals to the Windows device-management system, working with the adapter and any required device-specific drivers.
• Built-in Windows integration: Uses Microsoft’s Bluetooth stack to support device recognition and communication on compatible systems.
• Device Manager visibility: Appears under the Bluetooth category, where you can check its status, review driver details, and troubleshoot recognition errors.

How to Install

1. Check your Bluetooth adapter. Open Device Manager and expand the Bluetooth category. If the adapter is missing or shows a warning icon, install the correct Bluetooth driver from your PC or adapter manufacturer first. The enumerator cannot replace that hardware driver.

1. Look for the enumerator entry. Find Microsoft Bluetooth Enumerator in Device Manager. Open its Properties to check whether Windows reports that it is working properly. If it is, a separate installation is usually unnecessary.

1. Check for available updates. Use Windows Update to look for relevant system and driver updates. On Windows 11 and 10, also review optional driver updates. Update availability differs on older systems, particularly Windows 8 and 7.

1. Update or restore the component if needed. Right-click the enumerator and select Update driver to let Windows search for a compatible driver. If the entry remains faulty, uninstall that device entry and restart the computer so Windows can attempt to detect and reinstall it. Avoid removing driver packages unless you have a recovery plan.

1. Test your Bluetooth connection. Turn Bluetooth on and pair an accessory through Windows settings or Control Panel. If pairing still fails, check the adapter driver, accessory compatibility, and Bluetooth service status.

For a missing or damaged enumerator, Windows’ built-in repair and update tools are generally more appropriate than an unrelated standalone driver download. Bluetooth performance and supported features also depend on the adapter hardware and its manufacturer’s driver.
