Hi Kamil,

Its very easy to disable bluetooth. Just follow the below steps:

To turn it off, go toPC Settings > PC and Devices > Bluetooth. Or you can hit the Windows key and search for it from the Start screen and select Bluetooth settings from the results.



If you’re on the desktop, click the Bluetooth icon on the Taskbar and then select “Show Bluetooth Devices.”



Either way, you’ll get to the same spot where you need to be where you’ll see the devices that are connected or available to your laptop, Surface, or other device.
Flip the switch to Off to disable it.
 In fact, when you it off, all of the listed devices will disappear.
When you need to connect to a device again, just go to the same location and flip the switch to On again.



Regards,
Lokesh
