Use Device Manager to completely remove and let Windows reinstall the Bluetooth adapter, then, if needed, install the latest driver from the PC/adapter manufacturer.
- Uninstall the Bluetooth adapter
- Open Device Manager.
- Expand Bluetooth.
- Right‑click the Bluetooth adapter (may include the word “radio”) and select Uninstall device (confirm if prompted).
- Shut down the PC completely (not just restart). Wait a few seconds, then power it back on. Windows will try to reinstall the Bluetooth driver automatically.
- If the driver does not reinstall:
- Open Device Manager again.
- Select Action > Scan for hardware changes to force detection and reinstall.
- Roll back the driver (if Bluetooth worked before the Insider update)
- In Device Manager, expand Bluetooth and right‑click the Bluetooth adapter.
- Select Properties > Driver tab.
- If available, select Roll Back Driver and follow the on‑screen instructions.
- Install the latest OEM Bluetooth driver
- Go to the PC or motherboard manufacturer’s support website.
- Search using the exact device model.
- Download and install the latest Bluetooth driver for the Windows version currently installed.
- Restart the PC after installation.
If Bluetooth is still missing after these steps, repeat the uninstall from Device Manager, shut down fully, power back on, and then install the OEM driver again. For more general checks (e.g., Bluetooth icon missing, adapter not detected), follow the broader guidance in the Bluetooth troubleshooting article.
