What if the paired Bluetooth device does not work after the computer has removed or updated the Bluetooth driver?

First, from the Start menu, go to Control Panel, and click "Add Device" in the "category" view.

Second, adjust the Bluetooth device (for example, the phone here) to be searchable.

Third, after the computer search the Bluetooth device, click "Next".

The fourth step, appears the authentication code prompt, chooses "is", then clicks "Next", clicks on the handset to agree to match, then waits for the system to install the driver, can match successfully.

Fifth step, after the connection is successful, click "Delete Device" in the menu bar.

After the deletion is successful, repeat the first four steps, and then you can use it again after the match is successful.
