First identify the computer’s Bluetooth adapter, then try Windows’ built-in update tools; if those do not find the right driver, download the package for your exact PC model from its manufacturer’s official support site.
Important: Windows 10 support ended on October 14, 2025. Microsoft no longer provides free Windows Update software updates, technical assistance, or security fixes for Windows 10. A manufacturer may still offer a driver package, but that is not ongoing Windows support. See Microsoft’s Bluetooth driver guidance and its Bluetooth troubleshooting guidance.

1. Identify your Bluetooth adapter
- Open Start, search for Device Manager, and open it.
- Expand Bluetooth and look for the adapter name. Examples include “Intel(R) Wireless Bluetooth(R)” and “Realtek Bluetooth Adapter.” These are examples, not universal driver recommendations. The radio’s name and appropriate package depend on the PC’s hardware. See Microsoft’s guide to identifying Bluetooth hardware.
Entries such as Microsoft Bluetooth Enumerator or Bluetooth Device (RFCOMM Protocol TDI) are not the radio listing you need. If Bluetooth is not shown, check Other devices for an unknown device. If no likely adapter or unknown device appears, check the PC specifications or the manufacturer’s support information before choosing a driver; the computer may not include Bluetooth hardware.
2. Try Windows’ built-in driver update
- In Device Manager, right-click the Bluetooth adapter and choose Update driver > Search automatically for drivers.
- Follow any on-screen instructions and restart if prompted.
- Open Settings > Windows Update > Check for updates and install relevant available updates.
If Windows reports that the best driver is already installed, that does not establish that the PC maker has no newer model-specific package. Microsoft advises checking the manufacturer’s website when a newer driver may be available.

3. Download the matching driver from your PC maker
- Go to the computer manufacturer’s official support website and search by the PC’s model or service identifier.
- Select the Bluetooth driver that matches both the installed hardware and your Windows version. Do not assume that a package labelled Intel, Realtek, or another radio maker is suitable for every computer.
- Install it using the package format provided by the manufacturer:
- Executable package: Run the downloaded file and follow the manufacturer’s instructions.
- Individual driver files: Extract the files, then in Device Manager select Update driver > Browse my computer for drivers and choose the folder containing the driver files. Microsoft describes this route for packages that include files such as INF and SYS files.
Restart if prompted. Microsoft’s instructions point users to the PC manufacturer’s support site rather than unrelated driver-download mirrors: Update Bluetooth drivers in Windows and Fix Bluetooth problems in Windows.
4. Reinstall or roll back the driver if needed
Roll back after a recent update
If Bluetooth stopped working after a driver or Windows update, open the adapter’s Properties > Driver tab in Device Manager and select Roll Back Driver if the option is available.

Uninstall and let Windows try to reinstall
If rollback is unavailable or does not help, uninstall the Bluetooth adapter in Device Manager and restart the PC. Windows can attempt to reinstall the adapter. If it does not return, open Device Manager and select Action > Scan for hardware changes. Follow the detailed steps in Microsoft’s Bluetooth troubleshooting guide.

6. If the PC has no working Bluetooth hardware
An external USB Bluetooth adapter is a possible hardware fallback, not a driver download or a guaranteed fix. Check the adapter maker’s Windows 10 support and compatibility information for your PC before buying; Microsoft’s guidance on adding a hardware device to a Windows device does not endorse a particular adapter.
