Bluetooth Not Showing in Device Manager on Windows 10
I’ll be showing you the tutorial on Bluetooth Not Showing in Device Manager on Windows 10. The process is pretty much similar if you are using the older version of Windows like Windows 7 8 or 8.1
Before try this tutorial, please read my 1st tutorial : How to install Bluetooth driver in Windows 10
let’s get started, I would like to split this tutorial into three parts based on the difficulty level. so now let’s look at the first one. this is simple, you just need to open the device manager by using Windows 10 search. 
Now here at the right panel you will find device manager. Once you are on the device manager window go to view and choose show hidden devices. 
You may not see the Bluetooth driver right inside the device manager. Now choose the Bluetooth icon and right-click on it, then choose scan for hardware changes.
If this method didn’t work for you, then check the second one.
This is a bit advanced. We first need to know the laptop motherboard model number. If you know tha,t then do a google search to download the relevant drivers for your Bluetooth device, or else follow these steps visit cpuid.com and download the cpuid tool.
which is totally free and safe. Once it is downloaded , install it on your laptop. now open the cpuid tool and move to matherboard tab, and look for the model number.
Now open google.com and make a search like Bluetooth drivers followed by our motherboard model member, that we found using cpuid to download the right drivers. Install the downloaded Bluetooth drivers and restart the PC to get back the Bluetooth in device manager. If you still don’t get the Bluetooth icon back in device manager then go with third method.
Sorry I can’t guarantee that this method will fix the Bluetooth not showing in device manager issue. But give a try open the device manager by using Windows 10 search. Once you are on the device manager window, Move action and select add legacy hardware, click on next, and choose install.
The hardware that I manually select from a list, then choose next. Look for hardware named Bluetooth if you find any, just install it. If you don’t find, choose network adapters, and select next.
Here choose anyone named Bluetooth and try to install them. I have something inside the Microsoft label when the installation gets completed.
Restart the laptop and look for the Bluetooth in Device manager.
