Hi, since windows is multitasking OS, it must somehow switch between processes. But how is it done? Does windows include some kind of breakpoints into running programs, which should switch to other process? Becouse when program is executed, it takes control of CPU. So to enable multitasking OS must include some break instruction into the program. Am I right?
