Bluetooth device no longer showing in Device Manager

Hello @imacken,

I have lost my BT capability on my ASUS ROG STRIX Z590-F Gaming mobo.
The BT device no longer shows in DM.
This is what I have tried:
- reinstall drivers
- flash different BIOS, i.e. revert to previous version
- use rapr.exe to remove old BT drivers and reinstall
- looked in DM hidden devices, saw the BT device and uninstalled it.
Nothing seems to make a difference.
Any help greatly appreciated.

Have you got a System Restore Point prior to the problem that you could try?

Hello @imacken,

Thanks Paul. I'm not sure when the problem started as it is not something I use very often. Looking at the restore points available, the oldest one is from 30 March. I guess I could try that, but I'm never sure what gets reverted.
I wonder if this could be related to the constant message I get in WU about not being able to install KB5000842 optional update. It downloads and goes through the install, but then gives a message with error 0x8007000d.

So, I restored the oldest point, and it has made no difference.
Any ideas?

Hardware Troubleshooter:

Run the Hardware troubleshooter. This checks for common issues and makes sure that any new device[s] or hardware attached to your computer was installed correctly.

[1] Goto Control Panel.
[2] Type Troubleshooting in the search box.
[3] Click on Hardware and sound under Troubleshoot computer problems.
[4] Click on Hardware and devices under Devices.
[5] Click on Advanced on the Hardware and devices dialog box, select Run as administrator.
[6] Click Next [ follow on screen instructions to complete the Hardware and devices troubleshooter ].
[7] Try the device again.

I hope this helps!

Hello @imacken,

Here are the results of running the commands. No SFC errors 2nd time round.

Did you Restart the computer?

The ERROR code 0x8007000d relates to Invalid Data.

You could either look through the Windows Update Log to see if you can see where the problem is, and then try to fix it manually, OR, you could possibly perform an In-Place-Upgrade - Repair Install.

I found this thread for you which also covers this problem . . .

I hope this helps.
