I am not currently using windows 8, but I did some changes on my stepdad pc.
I did install the 8.1 update, changed the boot default to metro (his request) and then
configured to autologin without asking for a password.
The problem is that the password was changed to blank (nothing) and it worked well for a fews days.
Now the pc is booting and asking for a password and we cannot login ?
My experience with windows 2000,xp, and vista/7 never gave me such strange results.
May someone explain to me how to fix this ?
