Bluetooth not working

Hello Krishna010,

Thanks for the post! There are a couple of options that might help get your Bluetooth up and running again. As you mention the device stopped working after an update you may be able to roll back the device driver / reinstall the original software to regain functionality. Check out the Microsoft video guides below for instructions.
