Family Keylogger - this is the best choice, if you want to know what others are doing on your own computer while you are not at home (or office). Install Family Keylogger, set options "Start in hidden mode" and "Hide in task list", so that it makes itself invisible to anyone. After you return, you can just press keystroke to unhide. Family Keylogger - You have the right to Know!
MP3 Audio Recorder - Record any sound and audio stream from PC or internet.
