Windows 10: Bluetooth disappeared completely

Good afternoon.As stated in the title, my Bluetooth disappeared completely from my system. I don't know exactly when this happened because it's been years since I last used Bluetooth on my laptop. But today I wanted to, but it's completely gone. I can't find it under the notifications bar, it disappeared from my device manager, and when I run Troubleshoot, it says Bluetooth is not available on my device. If I go to services.msc, there is no "Bluetooth Support Service" option.My laptop is a Lenovo Ideapad Y50, bought in 2014, running Windows 10 Pro, version 2004, build 19041.1110.I went to the

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?

  In device manager, click on "view" tab and select "show hidden devices" and check whether Bluetooth device/driver is listed.

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.
