How can I transfer pictures from iphone to windows 10 pc via bluetooth

I have read the following instruction by Apple:

1. Firstly, go to your iPhone’s home and visit its Control Panel to turn on Bluetooth. You can also go to it Settings > Bluetooth and toggle the feature on from here. Also, make sure that your iPhone is “discoverable” beforehand.

2. Now, place it near your computer and go to its Start menu. Click on the gear icon to visit your Windows settings.

3. In your Windows settings, browse to Devices > Bluetooth and Other Devices and make sure the feature of Bluetooth is enabled.

4. Great! Once you have enabled Bluetooth, let your PC discover the nearby devices. Here, you can view a list of all the available devices, including your iPhone.

5. Select your iPhone from the list of available devices on your PC and authenticate the connection by entering a one-time generated code.

6. That’s it! Once both the devices are connected, you can go to your iPhone, and transfer anything to your PC.

But after successful pairing, I do not see the Bluetooth option on the iPhone when i select the send option. How can I send a picture to PC via Bluetooth, it can't be that difficult!
