Password protects your workstation or server with 'Transparent Screen Lock' while viewing programs that are running. Any attempts to access the system will display a message box to request the password. Prevent access via CRTL-ALT-DEL.

Use quick-launch icon to enable password protection anytime, or configure program like a screensaver to be enabled automatically at a preset time interval. NEW: supports for dual-monitor system configurations, embedded in-context help, tips of the day upon startup and keyboard shortcuts.
