My Bluetooth is gone on Windows 10

Question

I have a Samsung laptop, model NP300E5L-KF1BR with Windows 10 Education on Windows Insider Preview, with Slow Ring. My build is 16299.15.

I also have a Bluetooth mouse from Microsoft and since this afternoon, my Bluetooth simply went missing and my mouse didn't worked anymore.

There isn't a option to turn Bluetooth on anymore, and Troubleshooting says that my laptop doesn't have Bluetooth (which is false).

On Device Manager, Bluetooth only shows if I check to show hidden itens.

How can I get Bluetooth back?

Answer 1

I selected the Bluetooth device on Device Manager and removed it. Then I rebooted twice (on the first one Windows asked to reboot again) and it now works fine.

Answer 2

Please open Services.msc and check if the service Bluetooth Support Service is started automatic.

Fail to start the service, run commands as below to scan and repair system files:

sfc /scannow

Answer 3
