Bluetooth adapter device cannot start (code 10)

I ran the Hardware and Device troubleshooter. It did say that there was a problem with my Bluetooth device, however after troubleshooting it was not able to find a solution for the problem. I also tried updating the Bluetooth driver, but according to Windows my driver is already up to date. I also downloaded the latest versions from Intel's website and from AS Rock (my motherboard manufacturer), but they are the same as what is already installed. It looks to me as if the driver is not the problem. Are there any other possibilities?

Thanks for the help.

Thank you for the updates.

For us  to further check the issue, we'd like to know if you've tried performing the steps on how to troubleshoot Regsvr32 error messages. If so, what was the result? And can you also provide the update you've installed? To check, press Windows key + i > select Update & Security > click View installed update history.

We'll be waiting for your reply.

Hi team, I have same issue, have tried

1. Bluetooth support service - restart solution - this didn't work

2)Have tried uninstalling driver and installing new driver - this didn't work as on restart the old driver loads and error message appears

3. Have tried updating driver - this didn't work as its up to date

3)Have tried cmd: regsvr32 /u btmshellex.dll - this gives me fail to load error4_ in command prompt

Have an asus ux305

Don't really know where to go from here? Don't really want to start screwing round in the registry. This has ended badly in the past.

Update, I opened my computer today for round two of trying to repair my Bluetooth. Everything worked perfectly, immediately! I have no idea how it did it but it managed to fix itself overnight. Anyway i'm happy!

Since my PC did not have a lot of programs on it, I resolved the problem by reinstalling Windows. After this the bluetooth was working properly.

However, last night there was an update and when my PC was turned own this morning the Bluetooth is no longer working again. I did go through the process of checking for driver updates again, but everything appears to be up to date. I also tried the method that was suggested earlier about using btmshellex.dll registration error with the Regsvr32 tool. The error that I get with the Regsvr32 tool when I use the elevated command prompt and type "regsvr 32 /u btmshellex.dll" is that ...

"The module "btmshellex.dll" failed to load.

Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files.

The specified module could not be found."

Based on this and the link you provided, it looks like the btmshellex.dll file is not in the correct location or doesn't exist. I ran a search in windows file explorer over the entire C: drive and it was not able to find it.

Based on my update history, there were two updated installed last night.

One was the "2018-02 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4074588)"

The other was "Windows Malicious Software Removal Tool x64 - February 2018 (KB890830)"

Thanks for help. If there is anything else you need let me know.

Hi John,

The update could be causing a conflict between the Bluetooth and your computer. In the meantime, we suggest that you perform a System restore to the time that you've reinstalled your computer. Once done, you may stop the updates from installing on your computer. Here is the steps to disable the updates in command prompt:

1. Press the Windows key + X on your keyboard, then choose Command Prompt (Admin).
2. Type these commands one-by-one:net stop wuauservnet stop bitsnet stop dosvc
3. Close the command prompt and restart your computer once done.

Let us know if the issue persists after performing System restore to remove the update/s.
