Bluetooth allows Windows computers to connect wirelessly to headphones, earbuds, speakers, keyboards, mice, game controllers, smartphones, printers, and many other peripherals. When Bluetooth suddenly stops working, the cause is often a damaged, outdated, or missing Bluetooth driver.
Reinstalling the Bluetooth driver replaces corrupted files, refreshes Windows' hardware configuration, and often resolves pairing failures, missing Bluetooth settings, random disconnects, or devices that no longer appear.
This guide explains several ways to reinstall a Bluetooth driver in Windows 11 and Windows 10, including automatic installation through Windows Update, Device Manager, and manually installing the latest driver from your computer manufacturer.
Quick Answer
To reinstall a Bluetooth driver:
- Press Windows + X and open Device Manager.
- Expand Bluetooth.
- Right-click your Bluetooth adapter.
- Select Uninstall device.
- If available, check Attempt to remove the driver for this device.
- Restart Windows.
- Windows will automatically reinstall the Bluetooth driver during startup.
If Windows doesn't reinstall the driver, download the latest version from your PC manufacturer's support page or use Windows Update.
Why Reinstall a Bluetooth Driver?
The Bluetooth driver acts as the communication layer between Windows and your Bluetooth hardware. When the driver becomes corrupted or incompatible, Windows can no longer communicate correctly with the Bluetooth adapter.
Common causes include:
- Windows Updates
- Failed driver installations
- Malware removal
- System crashes
- Driver corruption
- Registry errors
- Upgrading from Windows 10 to Windows 11
- Installing incompatible Bluetooth software
Reinstalling the driver replaces damaged files and rebuilds the Bluetooth configuration without affecting your personal data.
Signs Your Bluetooth Driver Needs Reinstalling
You should consider reinstalling the Bluetooth driver if you notice:
- Bluetooth has disappeared from Settings
- Bluetooth is missing in Device Manager
- Devices won't pair
- Bluetooth keeps disconnecting
- Audio cuts in and out
- Bluetooth headphones have noticeable lag
- Windows displays Code 43 or Code 10 errors
- Bluetooth stopped working after a Windows update
Method 1: Reinstall Using Device Manager
Step 1 – Open Device Manager
Right-click the Start button and select Device Manager.
You can also press Windows + X and choose Device Manager.
Step 2 – Locate the Bluetooth Adapter
Expand the Bluetooth category.
Common adapters include:
- Intel Wireless Bluetooth
- Realtek Bluetooth Adapter
- Qualcomm Bluetooth
- MediaTek Bluetooth
- Broadcom Bluetooth
If Bluetooth isn't listed, select View > Show hidden devices.
Still nothing? Try Action > Scan for hardware changes.
Step 3 – Remove the Driver
Right-click the Bluetooth adapter.
Choose Uninstall device.
If Windows displays:
Attempt to remove the driver for this device
enable the checkbox before clicking Uninstall.
This removes both the installed driver and its associated software.
Step 4 – Restart Windows
Restart your computer.
During startup Windows detects the Bluetooth hardware and installs a compatible driver automatically.
This process normally takes less than a minute.
Step 5 – Confirm Installation
Return to Device Manager.
Your Bluetooth adapter should appear without a yellow warning icon.
Next, open:
Settings → Bluetooth & devices
Turn Bluetooth on and reconnect one of your devices.
Method 2: Install the Latest Driver from Your PC Manufacturer
Windows often installs a generic Bluetooth driver. While functional, it may lack performance improvements or compatibility fixes included by the manufacturer.

After Reinstalling
Once Bluetooth is working again:
- Reconnect your Bluetooth devices.
- Install all Windows Updates.
- Test several Bluetooth devices.
- Disable Bluetooth power saving in Device Manager if disconnects continue.
- Install future Bluetooth driver updates when released by your computer manufacturer.
- Create a System Restore point after confirming everything works correctly.
Frequently Asked Questions
