Some Windows 11/10 users with Bluetooth devices have been experiencing some problems recently. The issue comes up with an error that says-
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).

Microsoft Bluetooth driver not working (Code 52)
The key to fixing this error is to install a digitally signed Bluetooth A2DP file or the concerned driver file. Apart from that, there are other generic suggestions as well:
- Run Windows Optional Updates
- If you updated Windows, try uninstalling the latest Windows Update.
- Update the Bluetooth driver. You may download the Driver from Vendor’s Site
- If you updated your Bluetooth driver and the problem started then try rolling it back.
- Run System File Checker
- Run Bluetooth Troubleshooter
- Run Hardware and Devices Troubleshooter
- Revert the system or run System Restore
- Disable Driver Signature enforcement
As the last suggestion, we have said Disable Driver Signature enforcement. Suppose nothing works and you want to use this driver in any shape or form. In that case, disabling the Integrity check will forbid Windows from trying to verify the digital signature and integrity of the driver. But you could be compromising your computer’s security.
Restart your computer after every suggestion.
