Windows 8 Auto user log in problem.

I have some strange problem where every time I switch on my computer it will log into another user account and if I switch users it will automatically log in to the same account, and it is very frustrating, I had the normal auto log in problem before and a user messaged me on how to fix it which worked (Changing registry and inheritance but after awhile another problem has appeared. I thought it was just the same problem but the registry hasn't changed. I did find that if I disable the account it will eliminate this but I do not want to do that seeing as how one day it might randomly appear again on another username.
