I have a few questions...

1) From the initial start-up my computer logged on
without selecting an 'user' account or password (I
believe this was the default setting which I never
bothered to change). I tried to secure some files and in
the process have made it so that I have to at least
select an 'user' (though I have eliminated the need for a
password) in the welcome screen. How do I get rid of even
having to select an 'user'? I just want my computer to
logon automatically as it did before.

2) I know you can secure individual files (Word
documents) with a password. Can I do the same for an
entire folder without creating an 'user' as mentioned in
my question above? I know about 'hiding' a folder, but I
want a specific folder password protected.

Thank you.
