How to Unpair a Bluetooth Device on Your Windows Network
To see which Bluetooth devices are connected to your computer, click the Bluetooth icon in the notification area and choose the command Show Bluetooth Devices. You see the Bluetooth Devices window, which lists every gizmo that’s talking with your computer’s wireless Bluetooth radio.
Manage settings for a Bluetooth device by double-clicking its icon in the Bluetooth Devices window. Some devices, such as smartphones and other computers, have more options than the simpler devices, such as a keyboard or mouse.
To unpair a device, follow these steps:
Click the Bluetooth icon in the notification area and choose the command Show Bluetooth Devices.
Right-click a device in the window.
The device doesn’t need to be on to be unpaired. You'll notice that the devices show up in the window regardless of whether they’re on.
Choose the command Remove or Remove Device.
Click the Yes button in the Remove Device dialog box.
If prompted, type the administrator’s password or click the Continue button.
The device is unpaired and no longer appears in the Bluetooth Devices window.
You can always pair the device again.
Bluetooth devices can be paired with only one computer at a time.
