Windows 10: All bluetooth devices missing after update

All of my bluetooth devices that I had on my computor are now missing after updating my computer. They wont even show up when adding new devices. Could someone help me find out why this has happened?

Bluetooth device shows "Code 39" error in Device Manager on Windows 10 laptop

I'm encountering an issue with my Bluetooth device on my Windows 10 laptop. In Device Manager, the Bluetooth device is displaying an error message: "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)".

Here are some additional details about the problem:

• My laptop model is HP R007tx, and it is Bluetooth-capable.
  
• Despite the Bluetooth hardware being present, the device manager shows this error, indicating a problem with the device driver.
  
• When attempting to troubleshoot, I found that the Bluetooth driver's digital signature cannot be verified, suggesting a revoked signing certificate.
  

I've already tried the following troubleshooting steps without success:

• Reinstalling Bluetooth drivers obtained from the HP support website.
  
• Updating Windows and checking for driver updates.
  
• Restarting the laptop multiple times.
  
• Checking for dependencies and performing a System File Checker scan.
  

Despite these efforts, the error persists, and I'm unable to use Bluetooth functionality on my laptop.

Can anyone provide guidance on how to resolve the "Code 39" error with the Bluetooth device driver? Is there a way to address the issue with the driver's digital signature or any other troubleshooting steps I can try?

Your assistance would be greatly appreciated. Thank you!

Laptop details:

• Make and model: HP R007tx
  
• Operating system: Windows 10
  
• Bluetooth device error: "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)"
  

 

Bluetooth missing after update

Hi,

Thank you for replying.

One of the things you can try is to enable the Hidden devices and check if you see Bluetooth device. Refer the steps mentioned below:

1. Press Windows logo key + X, and select Device Manager.
2. Click on View and select Show hidden devices.
3. Expand Bluetooth and check if there are any hidden device.
4. If you find any device, right click on it and select Update Driver.

As you get that the best driver is already installed, I would suggest you to uninstall the Bluetooth driver completely from the computer and then install it from the Dell website. To do this, refer the steps mentioned below:

1. Press Windows logo key + X, and select
   Device Manager.
   
2. Expand Bluetooth and right click on the
   Bluetooth device and click on Uninstall
   device.
   
3. Now, download the driver from
   Dell website
   and install it.
   
4. Restart the computer.
   

Let us know how it goes.
