I tried the family version as suggested at the author's web site. It was a major disappointement because the free version won't hide the system tray icon at boot up. You can put put it in stealth mode during your current session but that doesn't permanently hide the system tray icon. So, it's only good if someone uses your computer before you reboot or shut down.
As soon as the computer reboots or restarts, the icon appears along with a gigantic balloon notice telling you about itself. What good is that? The freeware version is only useful, I guess, if you want to log your own keystrokes. What good would that be? I don't know. One other problem, you can easily find the program running in task manager even when the program is in stealth mode though most people wouldn't know what to look for, I guess.
