what is system interrupts in task manager

System Interrupts is an official part of the Windows operating system that manages the communication between your computer hardware and system. It is a placeholder used to display the system resources used by all the hardware interrupts happening on your PC. You can find it shown as a process in Task Manager. However, its not really a process in the traditional sense, but rather an aggregate placeholder used to display the system resources used by all the hardware interrupts happening on your PC. During normal operations, you might see the CPU usage of System Interrupts rise as high as 10% briefly before it settles back down to next to nothing. System Interrupts is an essential program component of the Windows Operating system that operates like an alert system for the CPU. It alerts or reminds the CPU of any priority scenario that needs the attention of the CPU. The CPU then stops or suspends its immediate task and saves it to take care of that high priority task to only return to the previous task when it's done.
