Thank you, my HP Elitebook 850 G3 had a faulty WiFi module, it would only turn on for a second and turn off all the time in Windows 10. Tried everything inc latest drivers and clean W10 install. This guide made it easier than I thought. Replaced WiFi module with a new ordered spare and it works perfectly now.
