I found a fix uninstalled ur Bluetooth driver, disable fast startup in power setting and then turn of your computer for 5 sec and turn it back on, Windows 10 will auto reinstall driver for you when your pc turn back on if not download the driver and install it urself. I believe fast startup doesn't turn off your pc completely when you restart or shut down and that's what costing the problem.

Credit does not go toward me, I found this somewhere else when I was searching on my phone but I forgot where.

I think I am having the same problem. I also have a custom built PC with an ASROCK Z270 Killer SLI motherboard. However when I type the commands that you posted above into cmd (running as administrator), I get an error that states that the module failed to load, and that it could not be found.

Is there anything I can do to fix this?

Hi John,

Just to check, are you having an issue with your Bluetooth?

We're looking forward to your reply.

Yes,

There was a small update that came out earlier this week. After the update the bluetooth on my desktop no longer works. When I check on the bluetooth driver (Intel(R) Wireless Bluetooth) in Device Manager, I get the same error that the original poster had. It says

"This device cannot start. (Code 10)"

"STATUS_DEVICE_POWER_FAILURE"

I am also running driver software 19.41.0.1

I am not able to connect any bluetooth enabled devices to the PC. I have not gotten this error before until the update that was downloaded and installed earlier this week. I tried uninstalling and reinstalling the driver software, but it still gives the same error. I was hoping that since I have the same motherboard as the original poster I would be able to use the same solution that he did in order to make it work. It doesn't look like I have that file on my system though as when running the command posted above in the command prompt, as administrator, I get an error that states that the module "btmshellex.dll" failed to load and that the specified module could not be found.

I don't think I am able to roll back from this update since it was not a major one.

Any recommendations on what I can do?

Thank you for your reply.

The error "This device cannot start. (Code 10)" usually appears when the device's hardware key contains a "FailReasonString" value, and the value string displays an error message defined by the hardware manufacturer.

To resolve this, please perform the following:

1. Run the hardware and device troubleshooter.
2. Update the Bluetooth driver.
