1. Update Your Bluetooth Drivers to the Latest Version

The most common reason that Bluetooth isn’t functioning on your system is that your Bluetooth adapter drivers are outdated. In this case, update your drivers to the latest version, and your issue will be fixed.

One quick and easy way to update your device drivers is by using Windows Update—this feature helps update drivers in addition to updating the Windows operating system.

To do that on Windows 11, launch Settings using Windows+i. In the left sidebar, select “Windows Update”. On the right pane, choose “Check for Updates”. Download and install the available updates. Then, select Advanced Options > Optional Updates. If there are any Bluetooth drivers here, download them. After that, restart your Windows 11 system.

On Windows 10, open Settings by pressing Windows+i, navigate to Update & Security > Windows Update, and click “Check for Updates”. Download and install the latest updates. Then, click “View Optional Updates” and install any Bluetooth drivers. After that, reboot your Windows 10 machine.

If your issue persists, you can manually download and install the drivers from your Bluetooth adapter manufacturer’s website. For example, if your adapter is from Intel, you can head to the Download Intel Drivers and Software page.

2. Fix Windows’ Corrupted System Files

Another reason a Bluetooth error occurs on a Windows PC is that your core system files are corrupted. When this happens, many built-in Windows features, like Bluetooth, stop working.

Luckily, you can fix your system’s damaged files with ease. Enter SFC (System File Checker), a built-in Windows tool that allows you to find and fix all the faulty system files on your computer. This way, you can resolve all your system file-related issues easily.

• To use that tool, first, open the Start Menu, find “Command Prompt”, and select “Run as Administrator”.
• In the “User Account Control” prompt, choose “Yes”.
• On the Command Prompt window, enter the following command and press Enter. This command downloads the files required to fix your system’s damaged files.

DISM.exe /Online /Cleanup-image /Restorehealth

When the above command has finished running, use the following command to begin finding and fixing your system’s corrupted files:

sfc /scannow

When your system files are fixed, restart your PC.

3. Disable the Built-In Bluetooth Adapter If You Have an External Adapter

If you’ve plugged an external Bluetooth adapter into your system and your system already has built-in Bluetooth functionality, your external device can cause conflict with your system. In this case, disable one of the adapters to resolve your problem.

If you don’t wish to use your external adapter, unplug it from your system. If you want to use the external one and want to disable the built-in adapter, here’s how to do that.

• Launch Device Manager on your system. Expand “Bluetooth”, right-click your built-in Bluetooth adapter, and choose “Disable Device”.
• In the open prompt, select “Yes”. This turns off your PC’s built-in Bluetooth feature.
• You can now plug your external Bluetooth adapter into your system and use it for all your Bluetooth-enabled devices.
