Actually the latest insider build (14332) removes all options to disable Cortana. Before you had to opt-in with "get to know me", now it's on at first boot and can't be turned off.
I recently tried to remove Cortana, because I personally find voice search worse than useless. I don't want my start menu searches being sent to MSFT. SteamOS for gaming can't come soon enough.
