Windows 10: Bluetooth drivers gone in device manager and cannot be reinstalled again. Windows 11

Good day, so when I updated my windows 11 laptop. MSI 14 b5m. I noticed that my Bluetooth is not working anymore and can't be turned on or off. I tried searching and doing all the troubleshooting with various ways like1. Checking device manager for view and show hidden devices, bluetooth device is not there2. Add legacy hardware - no bluetooth there3. Scan for hardware changes, not prompting anything to reinstall a bluetooth driver4. Add driver, I tried installing the ones from the MSI website but to no avail https://www.msi.com/Laptop/Modern-14-B5M/support?sub_product=Modern-14-B5M#driver&nbs

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 services and device manager

Hi Tina,

Having an incompatible driver causes functionality issues like what you are experiencing right now with your Bluetooth. To resolve such issue, we suggest that you uninstall and reinstall your Bluetooth drivers manually instead of letting Windows search for
an updated driver automatically. Here are the steps to do that:

• Visit your device manufacturer’s website to download the latest driver.
  
• Right-click on the Start button, then select Device Manager.
• Select Bluetooth, then the Bluetooth driver
  name.
• Right-click on driver and then select Uninstall device >Delete the driver software for this device check box >
  Uninstall.
• After uninstalling, right-click the driver that's having the issue, select
  Update driver > Browse my computer for driver software.
• Select Browse > look for the drivers you've just downloaded >
  OK.
• Select Next > follow the steps to install the driver >
  Close.
• Restart your computer.

Would you mind giving these steps a try and then informing me of the outcome?

Check if Bluetooth is Enabled in BIOS/UEFI

Sometimes, Bluetooth can be disabled in the BIOS/UEFI settings. To check this:

• Restart your computer and enter the BIOS/UEFI settings (usually by pressing a key like F2, F10, DEL, or ESC during startup).
  
• Look for Bluetooth settings and ensure it is enabled.
  
• Save changes and exit the BIOS/UEFI.
  

Show Hidden Devices in Device Manager

Your Bluetooth driver might be hidden in Device Manager:

• Press Windows + X and select Device Manager.
  
• Click on View and select Show hidden devices.
  
• Expand the Bluetooth section and see if your Bluetooth device appears. If it does, right-click and select Enable device.
  

Run the Bluetooth Troubleshooter

Windows has a built-in troubleshooter that can help identify and fix Bluetooth issues:

• Go to Settings > Update & Security > Troubleshoot.
  
• Select Bluetooth and click Run the troubleshooter.
  
• Follow the on-screen instructions to complete the troubleshooting process.
  

Scan for Hardware Changes

If the driver does not automatically reinstall:

• Open Device Manager.
  
• Click on Action and select Scan for hardware changes. This should prompt Windows to detect and reinstall the Bluetooth driver.
  

Check Windows Services

Ensure that the necessary Bluetooth services are running:

• Press Windows + R, type services.msc, and press Enter.
  
• Locate Bluetooth Support Service, Bluetooth Audio Gateway Service, and Bluetooth User Support Service.
  
• Ensure these services are running. If not, right-click each service, select Start, and set the Startup type to Automatic.
  

Reset Windows Services

Sometimes, resetting Windows services can help:

• Open Device Manager.
  
• Right-click on the Bluetooth adapter and select Uninstall device.
  
• Restart your computer and let Windows reinstall the driver automatically.
  

Check for Windows Updates

Ensure your Windows 10 is up to date:

• Go to Settings > Update & Security > Windows Update.
  
• Click Check for updates and install any available updates.
  

If none of these steps resolve the issue, it might be worth considering a system restore to a point when Bluetooth was working correctly, we can try it if all the steps above aren't working.
