Windows 10: How do I reinstall my Bluetooth driver on my Windows 10 laptop?

I have been trying to turn on my Bluetooth for this laptop for the past 2 months and the icon is not available in the action center and I have tried any and every solution. How do I get back my Bluetooth driver?

:)

My computer specs are as listed in the profile. I think all of you guys are correct. I don't have built-in Bluetooth in mobo.

I contacted skull candy headphones and thy have told me if I do not have built-in Bluetooth, I would need a dongle which supports at least a2dp. I do not know what the heck that means. I have a feeling I would need more than a cheap dongle.

Anyone suggest some a2dp adapters. I searched but don't know what a2dp is so couldn't make a decision

I should add that my laptop is pre Windows 10 and their isn't any Windows 10 drivers for it at all on the support page.
Windows 10 installed the drivers and all works as it should. Including BT.

• Support A2DP for Wireless Stereo Music Playback

Edit: This is a dongle with old BT version I see now, but I'm sure you can find a Asus BT4.0 version.

Edit2:

@aasim1111 I have this one, it doesn't show that it supports A2DP in the specs but I think it'll work, otherwise send a mail to Asus and ask.
