If you are concerned about privacy and if you use a computer in an environment where others may overlook what's on the screen or use the computer when you turn back : SparkLock is ideal for you.
SparkLock is a privacy software to instantly lock the computer and hide your screen ! Restore your desktop without losing anything by entering a password. Keep your data and computer private !
Why SparkLock is better than a regular session lock in Windows 2000 / XP :
(i) You can lock the screen by three quick and easy functions : by a single keystroke, by moving the mouse pointer from screen side to side like doing a screen wipe, by an inactivity delay like a screen saver.
(ii) When the system is locked with SparkLock NOBODY (even the system administrator) can use the computer without entering the password you have defined. All system control keys and processes are disabled.
(iii) Unlocking the computer is fast, no mouse click on an icon, no need to press the Enter key. It is also safe : the password is blindly entered without any password field on the screen. If an incorrect password is entered you must wait 5 seconds and reenter.
