How to disable Bluetooth option on Windows 10?

Hi Gopinath,

Thanks for posting on Microsoft Community. We regret the inconvenience caused and will assist you in resolving the issue.

Before we assist further, I would like to ask you a few questions:

1. When exactly are you getting “searching for Bluetooth devices” message?
2. Does the message appear randomly or on performing a particular task on the computer?

You may face the above issue if you have left the Bluetooth option enabled on the PC. On booting the PC the devices connect automatically if the option is enabled on the PC.

Follow the steps below to disable the option and check if the issue is resolved.

1. Press Windows logo + I keys on the keyboard to open Settings page and select Devices from the window.
2. From the left panel of the window, click on Bluetooth option and slide the bar to Off under Bluetooth on the right side panel.
3. Close the window and check if the changes are effective.
