This is a good document from Verge that goes over Windows 10 Hello. From what I understand about Hello is that it currently supports most fingerprint readers out there, but requires Intel’s REALSENSE infrared camera for facial recognition. Without having REALSENSE or a fingerprint reader unfortunately your 5548 isn’t going to be compatible with Microsoft’s Hello.     TB 
My laptop Dell 5548 which is compatible with Hello doesn't show me the option to set it up even after i set up a pin I uninstalled my Intel HD 5500 graphics to solve the Internal_Power_Error and now i cant find the driver necessary for windows hello i tried using Intel update utility
How to set up Windows Hello ?
