John2010: Should be at Control Panel>Devices and Printers; right click the Bluetooth device and fourth option down in the drop down menu toggles "Connect to Computer" and "Disconnect from Computer" according to the state of the connection.
Thanks for your reply, John. Right clicking on the device doesn't give me the connect/disconnect option, but I found that clicking on Sound Settings (or just Sound in Control Panel) took me to a page where I could toggle which device was the default.
Just as an aside, why can I not pin the sound icon in control panel to the task bar? Seems to be no way to do it.
