This article explains how to enable Bluetooth on Windows 10. Bluetooth comes built-in to all Windows 10 laptops, but if your desktop PC doesn't support Bluetooth, you can always add a Bluetooth adapter.

Before you can connect printers, headsets, and other devices wirelessly to your computer, make sure Bluetooth is turned on.

Open Windows Settings. Go to Start > Settings or use the keyboard shortcut Windows key+I.

Select Bluetooth & other devices from the left sidebar and make sure the Bluetooth switch is set to On.
