If anyone has figured this problem out, PLEASE HELP.
I remember having this issue when Win 8 was initially released but cannot remember how I finally got it to update. I do remember it was not an easy path to resolve.
I just recently had to install this OS on a laptop because Win 10 has nagging problem with dropping wifi connection on this Asus N56V.
I am so happy I no longer have to support Microsoft OS's in the work environment!
