Dude, you enlighten me, that happened to me too but it was during the time I jumped between win and Linux and one day did the wifi card just stop working and I couldn't figure out why, I tried many things without luck but some days it magicaly worked again and I haven't been in windows since and have never had that problem again. I don't know if I turned off fast boot (but I have done that many times so it is likely), so it could have been an update that turned it on. I will remember this if it happens to someone or myself again. Thank you!
