drivers – Bluetooth is turned off. Windows Update, Device Manager and Services unable to turn it on

Starting yesterday and in the middle of work (not after a specific update), I noticed that my Bluetooth keyboard stopped working. And then saw that Bluetooth is turned off.

So, I tried a few restarts to no avail.

Here is a list of other measures I have taken:

  • Windows Update and all the driver updates
  • Dell Update of all the drivers’ Scan Device Manager for any hardware changes
  • Starting all 3 Bluetooth-related services on Services

Each measure was followed by a restart.

But despite all, I am unable to turn Bluetooth on. There is no toggle button appearing on Bluetooth and other devices settings on my Windows.

I have several Bluetooth devices. So, this is not only about the keyboard. None of the connected Bluetooth devices are working.

Bluetooth does not appear in Action Center, either.
