Go to google and look up keystroker tracker or something like that.... There is software you can download and install for free. It runs in the background, you don't see it running on the toolbar or the task manager. It access it you set up hot keys. It will track the keystrokes made on the computer-- ie: passowrds! and it will record IM conversations, and all the history on the computer.
Just a reminder, if it is a shared computer (you and another person) you can always use the hot key controls and turn it off while you are on the computer, so no one gains the info about you!
Good luck.
