Hi,
Good day! My name is Santosh. I am Microsoft user like you. I will be glad to help you.
Please go to Windows setting by pressing Win+I key and click on Devices. Here you will find Bluetooth option. Bluetooth option should be turned on. Here is a screenshot below.
If you do not find Bluetooth option, then you have to download Bluetooth driver
You have to go to your PC's manufacturer's website where you can type model number of your PC, and you can download Bluetooth driver. You can install Bluetooth driver also.
Here is a Microsoft link for more information.

Santosh
