Hp Probook 450 g2 bluetooth could not find device


I have installed updated driver for HP Probook 4520 G2 but i am neither able to search any device nor laptop is searchable from any device.

I have already uninstall and reinstall drivers after reboot. Already checked options to “Allow Bluetooth Devices to find this computer” & “Allow bluetooth devices to connect to this computer”.

Device managers shows no issues but it keep searching and searching for hours :frowning:

I tried to play with Registry by following below link


but guess what… now i can’t even install bluetooth driver because i have deleted class.

Any body recommend me cheap but reliable bluetooth USB dongle ?
