In the last years it has become very difficult to use old games or programs due to the speed of new processors. Many old software programs(like clipper or old pascal applications) crash with errors like "runtime error" , "overflow error" , etc... Many of the greatest games have become too slow to be played or they don't run at all. So I decided to make CPUKILLER , a program that can slow down your computer up to 98% offering in many cases the solution to those problems. How it works: It is very simple, CPUKILLER takes the control of your processor and makes the resource occupancy grow enough to slow down the execution of other applications. When you want your computer to return at the normal speed you have only to stop CPUKILLER. You can even configure CPUKILLER to launch automatically with your old programs and to terminate itself when they exit!
