QualityTime

Quality Time parental control software solves all of those arguments about computer usage in the home. Now you can limit usage to particular times of the day, and limit individuals to an amount of time within those periods, without having to have an argument.
Let Quality Time do the rest! Whenever the computer starts up, Quality Time is loaded before any other programs. Just select your account name, enter your password, and press the Login button, and the clock starts running.
When a user's time is up, the software pops back on top, and prevents them from running any programs. It also prevents inquisitive users from ending the program with CTRL+ALT+DEL or by switching away to another program. You can be assured that the computer will only be accessed during the allowed times.
Quality Time is now available in German and English, and will speak configurable warnings at 5 minutes and one minute before time runs out, using Microsoft Agent Technology.
