Set the program to start automatically (minimized in the system tray) every time you start your computer.
  Set the program to always start in User mode. User mode allows a user to run only those programs and applications that have been allowed by the Administrator. Users do not have access to Preferences, etc.. If this box is cleared the program always starts in Administrator mode.
  Terminate your system if a User attempts to shut down System Safety Monitor.
  Allow a user to start any application (except of Black-Listed) even if the program is running in User mode.
Caution: This partially removes program firewalling.

  Set an Administrator password. Only the Administrator can make changes to the program's settings, including shutting the program down. Setting a password prevents a user from switching to Administrator mode.

The first time you set a password, enter it in the New and Confirm boxes only.

If at any time you want to change your password, fill in all three boxes.

If you want to remove password protection, enter the current password in the Old box and leave the others blank.

Passwords are case sensitive ("R" is not the same as "r").

When choosing a password, try to follow the basic rules for a good secure password û it should be at least 8 characters long; contain a mix of letters, numbers and other keyboard characters; and not be a word that can be found in any dictionary. Avoid using your name, address, phone number, postal or zip code. These kinds of passwords are easy to crack.

  Assign a hotkey to show/hide the system tray icon.
  Show/hide the system tray icon at startup.

Note: While either of these two options will mean one less icon in your tray, and setting an Administrator password and hiding the program icon obviously adds an extra level of security, you would now also have to remember the key sequence to show the icon. You might prefer either or both of the above options if you don't need the solid security of an Administrator password or can't be bothered with the hassle, but still want to hide the program from the casual (not power) user and so prevent them from altering your preferences.
