AUTO WINDOWS LOGIN: Give the Admin the opportunity to match up the Net Nanny users to the Windows accounts on the computer, once this is done Net Nanny no longer prompts for a password to login for internet access. The user is logged in automatically once the internet is accessed.
This feature is best used when there are multiple Windows users on the computer.

AUTO CLIENT LOGIN: Allows the user to login one time for Internet Access, but then logs in that user every time thereafter that the computers is restarted.
