No mercy is a program which effectively limits the time spent in front of computer. The program is dedicated to parents whose children spend too much time with computer and in front of the screen. The program not only informs a user how long he spent looking at the screen, but also switches off a computer and makes impossible to continue working of the program in Windows. No mercy is the program which can control and limit access to the computer in a very good way. The program is really easy to use and user doesn't need to have advance knowledge about Windows operating system.

In the program you have to set day's limit of the time, which can be used for working on the computer. This limit can be different for every user of computer. The limit doesn't have to be used immediately. Each person who was limited by the program No mercy can use the computer every time and he doesn't have to use the whole time which is dedicated for this person - the person can use it "in parts". When limit is used up, the computer will switch off and after restart of the system user will have at the most one minute from logging on to another shutdown of the computer. This short period of the time is sufficient for the authorized user who can change settings in the program No mercy if only it is needed (e.g to increase the user's time limit).
