Windows 10 DriverStore Help - Missing Driver and Unknown Device in Device Manager

[mikeynavy1976]

I'm trying to avoid having to do a clean install if possible. Windows 10 updated to 1803 yesterday on three of my machines. One machine now shows an "Unknown Device" in Device Manager and I've tried everything I can think of to troubleshoot. Please advise on next step before I give up and download a new Windows iso (hopefully updated on Windows site to 1803):

- Unknown device has Hardware ID of BTH\MS_BTHL2CAP. Researching online this is supposedly the Microsoft Bluetooth Protocol Support device.
- Searching online has been unsuccessful in finding the *.inf with corresponding driver. It is a Microsoft driver that appears to normally come with Windows.
- My Bluetooth device is an Intel 8260 and I have tried a few Intel drivers to see if it would correct the issue...no luck.
- I don't use Bluetooth devices with the laptop so I'm not sure if there is an execution problem...more of OCD seeing the yellow exclamation.
- My other two machines, also updated to 1803, don't show the issue with their Bluetooth adapters, and I don't see the driver inf in their driverstore folders (I was hoping I could cut and paste).
- SFC/scannow reported 0 integrity violations
- Windows Bluetooth Troubleshooter reported 0 issues.

Other recommendations?

what make/model laptop is having the problem? It might be a problem specific to the model itself and since the Spring Creators edition is just new, you might have hit it first.. or not.

MERGED QUESTION
Question from mikeynavy1976 : "Windows 10 1803 Device Driver Error - Please help"

I've encountered a few bugs after installing the April Update to Windows 10 1803. Right now the most notable one is that on one of my laptops device manager is showing an "unknown device" with hardware ID BTH\MS_BTHL2CAP. Researching online this is supposedly the Microsoft Bluetooth Protocol Support device. The error says there is no driver. Uninstalling it is only temporary as is reinstalling the Bluetooth driver for the actual device (Intel 8260). I can't seem to find anywhere to download and manually install the driver. Can someone please help point me to the driver or how to fix the issue? Thanks.

You say you don't use bluetooth anyway, so why not just ignore the issue :/

Colif...Per my original post, the Bluetooth is embedded in an Intel 8260 adapter. The laptop is a Dell XPS 13 9350. I've tried several Intel and Dell drivers to see if one of them would make the issue go away but the missing driver is from Microsoft and somehow didn't migrate with the update. I"m stumped on why I can't find it online either...nowhere to download it to fix it. I've looked on a few other forums and it appears I'm not the only one experiencing this issue either.

Phillip Corcoran...I could ignore but I'm also not the only one who has OCD or is annoyed by seeing that "Yellow triangle with exclamation mark" and knowing something isn't right

Have you checked to see if your device has been tested for 1803?

http://www.dell.com/support/article/au/en/aubsd1/sln297954/dell-computers-tested-for-windows-10-april-2018-update-and-previous-versions-of-windows-10?lang=en

notices this and links so we don't duplicate answers: https://www.tenforums.com/drivers-hardware/109146-unknown-device-device-manager-after-1803-update.html - seems you not alone as 1 guy there says he has same problem. Could be the driver isn't signed to work with win 10, I have noticed that other drivers that worked before this patch are not now. Dell may need to update the drivers.

Colif...thanks for the link. My model, 9350, is listed as tested but I may go to Dell Community and see if someone there knows as well.

Well a positive update....1st...this issue seems to have occurred on a variety of Dell laptops...so not an isolated incident. Fortunately, someone on tenforums recommended an in-place upgrade repair and it worked. For anyone else that happens upon this thread with the same issue, here's the link:
