It would be great if you just had to remove the single entry under “Bluetooth”, but unfortunately you’ll also have to go into quite a few more places. When it opens, Go to the View menu and select “Show hidden devices” as in the screenshot below. To open the device manager, go to the start menu (CTRL+ESC, or press the dedicated Win-key) and type “Device Manager”. Whenever Windows gets errors like this, you’ll need to leave the glossy interface of Windows 10 and open one of those programs that have been around since Windows 95 - the Device Manager. Instead, the audio device just displayed the message “Removal failed”. In theory, I should just click the Remove Device button and then re-pair the Bose QC35 II by holding the power button forward a little and then re-adding it in Windows. For some reason, this is not as smooth as it should be. Anyway - if you change bluetooth adapters, the connection may not work so you’ll need to reinstall the device. My main beef with these headsets are how annoying it is that it speaks out loud the name of anythng it tries to connect to. If you have a Bose headset like I have, you’re not very likely to ever have a problem. After doing this, my headset wouldn’t work and the Bose headset Audio device refused to uninstall. I recently changed from the terrible internal Bluetooth radio on my Asus motherboard to a dirt cheap Bluetooth 4 dongle.
