Have you ever opened up Task Manager and noticed the System Idle Process is using 90% or more of your CPU? Contrary to what you might think, that’s not a bad thing. Here’s what that process actually does.

If you’ve ever poked around in the Task Manager—Windows 10 users have to look under the “Details” tab—you’ll see that the System Idle Process is using most, if not all, of your CPU. But the System Idle Process is just that; an idling process made by the operating system. Without this process constantly keeping your processor occupied with something to do, your system could potentially freeze.
In other words, the CPU resources used by the System Idle Process are just the CPU resources that aren’t being used. If programs are using 5% of your CPU, the System Idle Process will be using 95% of your CPU. You can think of it as a simple placeholder. That’s why the Task Manager describes this process as the “percentage of time the processor is idle.” It has a PID (process identifier) of 0.
Windows hides the System Idle Process information from the normal Processes tab in Windows 10’s Task Manager to keep things simple, but it’s still shown on the Details tab.
There are very few things the average user does to cause a processor to run at full capacity. Even a modest modern processor has more than enough capacity for even the most challenging game, image or video editor or any other program you care to use. So it can be annoying when Windows itself utilizes all your processor causing your computer to slow down. When that process is called the ‘System Idle Process’, the irony is not lost on us.
