Intel Bluetooth Driver Code 19 (incomplete or damaged registry entries)


I've just updated to Windows 1709 (Creator Edition Fall Update) and installed latest BT drivers (BT_20.0.0_64_Win10) for AC7260 wireless.

It works fine for a few shutdown/reboot or hibernate/resume cycles but soon the Device is shown in Device Manager with the dread yellow exclamation mark, and display of properties reports:

Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)

Strangely the driver version is displayed as ???

If I uninstall the driver and reinstall (Scan for Hardware Changes or reboot), then it will work again for a while.

Any suggestions as to how this problem can be circumvented?

Hello perdrix,

We understand you're having issues with the Bluetooth® module of your Intel® Dual Band Wireless-AC 7260, resulting in an Error Code 19 on Device Manager.

The reason why your adapter is showing driver version is because what you download is a software package containing the latest drivers for all of our active wireless adapters. This will result in a different driver version being installed depending on your adapter model, https://www.intel.com/content/www/us/en/support/articles/000005559/network-and-i-o/wireless-networki... more info.

The recommended troubleshooting for this error code is to perform a clean installation of the device drivers.

1. Open Device Manager > Bluetooth® > Intel® Wireless Bluetooth® 4.0


2. Right click on your adapter and choose to Uninstall, if given the option, select to "Delete the driver software for this device."


3. Go to Programs and Features in the Control Panel, or Apps & Features in Windows* Settings. Uninstall the Intel® PROSet/Wireless Software for Bluetooth® Technology.


4. Reboot.


5. Download and install the latest https://downloadcenter.intel.com/download/27391/Wireless-Intel-Wireless-Bluetooth-for-Windows-10?v=t Intel® Wireless Bluetooth® for Windows® 10, version 20.10.0

Please let us know if this resolves the error.
