Hi! I find interesting spy software. Here description from their site.
---------------------------------------------------------------

Desktop Spy Agent is an invisible and easy-to-use PC activity monitoring
tool that captures screenshots of the active application window or the
entire desktop at the predefined time intervals varying from 1 second to
several hours and saves the recorded images to a specified directory on
the hard drive. The images can later be viewed with the built-in image
viewer or any external software (Desktop Spy Agent can save screenshots
either as Windows bitmaps or in the industry standard JPEG format with
custom compression level).
This tiny and smart spy software can be used at home to control what the
members of your family do on the PC when you are not watching. It is also
a great employee monitoring and surveillance tool that can help you
prevent the misuse of corporate resources and other, more serious,
incidents.
Desktop Spy loads on Windows startup and quietly runs in the background
completely hidden from everyone but you. It uses very little resources and
does not degrade the performance of the system it is running on. The
customizable hot keys enable you to start and stop monitoring, display and
hide the program window, view the captured images or quit the program
completely.
The program can also be password-protected, so that even if someone learns
the hot key, he or she will not be able to disable the snooper or modify
any of its settings.
