To remove an item from the drop-down lists that appear, highlight the option
and press the Delete key. It will then be removed from the list permanently.
Password fields are never stored in such a way. The only time passwords are
stored is when you enter a username/password combination and it asks you the
first time if you wish to store it or not. This is true for both web-based
forms, and HTTP security (where a dialog box pops open asking you the
username and password).
According to Microsoft, the database (call it what you like) where all this
information is stored is encrypted, so you cannot just go to a random
machine and grab all the data - you must go to a form that has the proper
field names in order to get the information.
