Windows 10: Unable to delete Bluetooth driver related Registry Keys

Hello,

I've been unable to use Bluetooth related services since the upgrade to the Creators Update(1703). The device manger returns a Code19 error saying "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged". I've since tried various workarounds but have had no luck so far. So, I'm hoping a complete reset of anything Bluetooth related in the registry will fix the issue.

As suggested here I've manged to delete all the relevant keys except for one particular key named BTHENUM. As you can see in the screenshot attached, the key contains a number of subkeys. Even more show up upon taking ownership of 'properties'. Since there are close to a hundred keys (maybe more), I've tried using the command line tool (subInacl.exe) to take ownership/make necessary changes to the keys but the command fails with some keys working and the rest not. The only way out for now is to take ownership/delete individually which is a nightmare.

I would like to know if there's a quicker way to get this done other than a clean install.

Note: I've tried deleting the keys in safe mode and via the built-in administrator account without success. I've also uninstalled all hidden BT drivers from Device Manager.


Any advice is appreciated.

Thanks

Bluetooth Device Automatically Reinstalls and does not work

Figured it out, replying just in case anyone runs into the same problem.

Here is what worked for me.

1) Go into device manager, right click on the stuck device, go to properties and in the top menu select events. There should be an event Device Install Requested. In information for that event the MAC address of the device is listed Device BTHENUM\Dev_<MAC>.
Write down the MAC address.

2) Unplug dongle

3) Stop all Bluetooth related services. Windows+R keys to open the Run dialog, type services.msc,
press Enter. I had Bluetooth Service, Bluetooth Support Service, and Bluetooth Driver Management Service.

4) Uninstall all device and dongle related drivers through device manager. Make sure to click show hidden devices in the view menu and uninstall everything Bluetooth related including
COM ports, RFCOMM, and PAN.

5) Use Registrar Registry Manager (Resplendence Software - Registrar Registry Manager) and search the entire registry for the MAC address of the device in a single string, for example "0006667624b4". Delete every single entry, careful here to not delete anything unrelated
to the device by accident. The reason to use Registrar Registry Manager is the Windows registry editor will not allow you to delete some of the keys due to null characters, no matter what permissions you have.

6) This is what I missed before when I tried manually cleaning registry. Search for the MAC address again but type it in HEX format for example "00:06:66:76:24:b4". This should find more entries, delete all, again be careful, make sure its Bluetooth related.

7) Reboot, plug dongle back in, install dongle drivers. The device should be gone and you should be able to pair it to the computer again.

Good luck everyone.

 

Problems installing updates - Windows 10 Home Version 1607

AdwCleaner removed things related to a coupon printer (files, service, folders) and leftover folders related to AVG. It also deleted several registry keys, many of which appear to be related to the coupon printer(s?). There are a few other keys, but I can't
really tell what they are by name or location on the C: drive

JRT deleted three files (look like they were related to AVG updates), two registry keys, and one registry value

Malware Bytes turned up nothing

Hitman deleted a ton of cookies and several PUPs. It looks like they may have been registry keys or values, all related to that coupon printer.

 

Download ExecTI
and run regedit as TrustedInstaller to see if you can delete the whole thing.

 

Thanks for the reply. Will see if it works.

Edit: The tool worked. I could delete the keys...As for Bluetooth itself, I have to see if a re-installation works. Fingers crossed it will. If not I'll be back again *Smile
