A number of users have recently reported that they were going through an issue with their Bluetooth devices on their Windows 10 computers. This issue involves an error saying,
“Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52).”
If you are one of the users who encountered this kind of error on your Windows 10 computer, read on as this post will guide you on how you can fix this Bluetooth error. According to security experts, the key to fixing this error is to sign the Bluetooth A2DP files with the built-in tool, System File Checker. Apart from that, you could also run the Hardware and Devices troubleshooter or perform System Restore, as well as update or reinstall the concerned drivers.

- From there, verify if the Service status is showing “Running” or “Stopped”. If it’s the latter, you have to click the Start button.
- Lastly, check if the Startup type is set to Manual.
Option 2 – Try running System File Checker or SFC scan
You could also run System File Checker or SFC scan to fix the Bluetooth error. It is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

- After opening Command Prompt, type in sfc /scannow
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

- Windows Resource Protection found corrupt files but was unable to fix some of them.
Option 3 – Try to perform System Restore
You might also want to perform System Restore as the error might be caused by system modifications. Thus, to undo them, you can use System Restore. Run it using these steps:

Option 4 – Try running the Hardware and Devices Troubleshooter
The next thing you can do to fix the problem is to run the Hardware and Devices troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the Bluetooth error. To use it, refer to these steps:
