Most desktop computers and laptops come with a built-in Bluetooth adapter. Although Bluetooth is not as useful as Wi-Fi these days, your PC must have Bluetooth to connect all kinds of Bluetooth devices (such as the headset, speaker, and phone) to your PC.

If you have turned on the Bluetooth but are unable to connect an external Bluetooth device to your PC or unable to pair your phone with your PC, it could be because of a faulty or corrupt Bluetooth driver.

While we recommend trying other troubleshooting methods out there before uninstalling or reinstalling the Bluetooth adapter driver, uninstalling and then reinstalling the Bluetooth driver fixes the issue in most cases.
