Windows 10: Bluetooth device suddenly missing after update.

Hi all,My bluetooth device is suddenly missing today when I booted up the PC.I am running Windows 10 version 21H1.The bluetooth toggle button is missing from the Bluetooth and other devices settings page.Device manager is listing a bluetooth device but only after i view hidden items, and those items all say "Currently, this hardware device is not connected to the computer. Code 45 To fix this problem, reconnect this hardware device to the computer."Any help would be greatly appreciated.

Bluetooth Suddenly Disappeared - from settings & device manager

Number 1: Open up the devices window (search for Device Manager, and you will get the window).





Number 2: Open up the View Menu. When I selected "Show Hidden Devices", my Bluetooth devices and installed drivers appeared.





Now you should see Bluetooth on the device list. Click the arrow to open up the selections:






Number 3: I double clicked each of the 'devices' under Bluetooth (there were several on that particular computer). The message told me that the devices were'disconnected'. I right-clicked each of them and selected 'Update Driver". I chose to search the web for the updated drivers:





It updated one driver, but Bluetooth was still disconnected.

Number 4: Finally, I went to the web-site of the maker of that laptop and downloaded the most recent drivers to the machine. I unzipped them, and selected 'Update Drivers' again for the Bluetooth device on the machine (which unfortunately had a generic name like 'Win USB Bluetooth Device' so I wasn't sure I was selecting the correct thing).

This time, however, I chose "Browse my computer for driver software", and chose the folder to which I unzipped the downloaded driver. The driver updated and, lo and behold, the device connected.

I'm giving you such a detailed description because it took me a couple of hours to find where the problem lay and solve it. Hope this helps you! If I've been unclear, please let me know!

Bluetooth missing after update

Hi,

Thank you for replying.

One of the things you can try is to enable the Hidden devices and check if you see Bluetooth device. Refer the steps mentioned below:

1. Press Windows logo key + X, and select Device Manager.
2. Click on View and select Show hidden devices.
3. Expand Bluetooth and check if there are any hidden device.
4. If you find any device, right click on it and select Update Driver.

As you get that the best driver is already installed, I would suggest you to uninstall the Bluetooth driver completely from the computer and then install it from the Dell website. To do this, refer the steps mentioned below:

1. Press Windows logo key + X, and select
   Device Manager.
   
2. Expand Bluetooth and right click on the
   Bluetooth device and click on Uninstall
   device.
   
3. Now, download the driver from
   Dell website
   and install it.
   
4. Restart the computer.
   

Let us know how it goes.
