Not sure which forum is correct for this, but: I have Windows 10 on a Dell Optiplex 3020 desktop. It has no Bluetooth built in, so I have a little dongle that plugs into a USB port. I want to use a Bluetooth mouse. I can manually pair and connect it (using a wired mouse and 'Bluetooth & other devices' in Windows Settings) once Windows is running, but is there a way to make it automatically connect every time without doing this?
