A window operating system for casement and awning windows has two actuators that are connected to be controlled by one crank to operate simultaneously. The system is modular and the crank is preferably part of a crank assembly that is a separate component from the actuators. In a further embodiment, the operating system has at least one actuator with a crank assembly to operate the actuator being located at a different location on a window frame from the actuator. With a modular system, there are numerous variations for location and number of locks and the location of the crank assembly as well as other components. The system still further describes a lock for a window operating system.
