If your Bluetooth is not working on Windows 11, missing from the quick settings, Bluetooth icon disappeared, or your Bluetooth devices won’t connect, this step-by-step tutorial will help you fix it. This guide also works on Windows 10 and most laptops and desktop PCs (Dell, HP, Lenovo, Acer, ASUS, etc.).

In this video, I show how to:

Restart Bluetooth services the correct way

Use Windows Troubleshooter to auto-detect problems
