Per R.H. Breener:
It didn't work anyway. I unchecked the box but still have to use my
password. I wish I could have found a LP with W7 but no one was selling
them. This W8 is the pits.

I don't know enough to comment on the PW situation, but would add one
more caveat: If your login is associated with a Microsoft account, get
rid of that association.

When I first booted up mine, I stepped through all the prompts and one
of them led me into setting up my own Microsoft account and the laptop
wound up being linked to that account.

Bad Idea.... later on, for whatever reason, somebody can decide that
something is not right with that account and you will get the dreaded
"Cannot log in..." (or somesuch)

At that point you may be SOL - either if you cannot recall the PW last
used to log in to the laptop when it was offline or for some other
reason I have no clue about.

Google "windows 8.1 how to remove Microsoft account" for instructions.

Maybe somebody who knows can comment on the benefit(s) of being
connected to a Microsoft account.... all I can come up with are
costs....
