This program is mainly aimed at parents wanting to control the time spent by their children on their computer (although other uses can be considered, of course). It allows you to specify when and for how much time a Windows session, the Internet connection or a program may be running for a given period of time (a period being a day or a week).
It also allows you to define time allowances for specific programs (including the Internet connection) as well as time slots outside of which the restricted program, including Windows, may not be executed.
