Windows 10: Bluetooth completely disappeared

This happened a few months ago now but one day, my bluetooth stopped connecting to my headphones. I decided to restart my laptop to fix this issue but instead, bluetooth completely vanished from settings. I tried to uninstall bluetooth from device manager, but when I clicked "check for hardware changes" my laptop did absolutely nothing. I've gone to the services to turn on the bluetooth support, still did nothing. I've tried to manually install bluetooth again but that didn't do anything either. No matter how many times I troubleshoot or restart my laptop, bluetooth never reinstalls itself lik

Bluetooth disappeared

Hi Jenny,

We appreciate you for being a part of Windows 10.

Before proceeding, we need more information to help you better.

• 
  Did you checked whether the Bluetooth device is listed under hidden devices in Device manager?
  
• 
  Have you checked whether the Bluetooth driver is listed under installed programs under Programs and features? (As you have reinstalled the Bluetooth.)
  
• 
  Does the Bluetooth disappeared after you have started to use Wacom Bluetooth keyboard?
  

Note:

• 
  In device manager, click on "view" tab and select "show hidden devices" and check whether Bluetooth device/driver is listed.
  
• 
  To check the drivers installed in Programs and features, Press
  Windows + X keys on the keyboard and select Programs and features and check whether the Bluetooth driver is installed.

Thank you.

 

Windows Updated(16299.309).KB4088776 Restart is required to complete.

Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

Thanks for the suggestions and for the time to respond Best regards.


And thanks for the tip of that program, I'll have it on my list.

 

No bluetooth after system restore

Thank you for your reply.

I mean I have used a Windows system restore point. I tried restoring bluetooth with commands in CMD (sfc/scannow; DISM /Online.....) and by updating and uninstalling devices in the device manager. Update did not work. Uninstalling bluetooth devices made Bluetooth disappear out of the hidden devices list.
All my steps I took worked but did not change anything in my bluetooth device list.

I am using the bluetooth of my mainboard. MSI Z370M Gaming Pro AC
My guess would be, that disabling the bluetooth network adapter before using a system restore point, disabled Bluetooth after using the system restore point.

In the device manager I get this message in the USB Device list for a unknown USB Device:
Windows has stopped this device because it has reported problems. (Code 43)
A request for the USB device descriptor failed.
