If your RAM use is high and your PC is running slowly, an app may be the cause of the problem. Microsoft suggests to kill the Runtime Broker Process if it uses more than 15% of memory. It should only use a few megabytes of memory, but in some cases, a faulty app might cause Runtime Broker to use up to a gigabyte of RAM or more. Runtime Broker is a Windows process in Task Manager that helps manage permissions on your PC for apps from Windows Store. It may also use a lot of memory, especially if a faulty app is the root cause of the issue: The System Idle Process should be at the top when your computer's not very busy.Reports started to come up as early as 2015 that Runtime Broker was causing high CPU loads on Windows 10, and as early as 2012 that it was using a lot of memory on Windows 8.

In Windows 7 and Windows 8 start the Task manager (press CTRL-SHIFT-ESC), tick the 'Show processes from all users' box and click the CPU header to sort the list.
Sort by CPU when your PC isn't doing much and the System Idle Process should be at the top 'using' most of your CPU's resources.

In Windows 10 start the Task Manager (press CTRL-SHIFT-ESC) and click on the Details tab. To see the System Idle Process in action depends on the OS that you're running. So, it can now reduce processor clock speed and implement other power saving options. For example, it can be used to shut down parts of a CPU that aren't currently being used when a 'real' task comes in, the CPU wakes up all of its parts.Īs processors have become more complicated and more efficient, the System Idle Process has also improved. Secondly, the System Idle Process can be used to run specific power-saving tasks. The first is that this helps the task scheduler run, as without this process there may be a time when the task scheduler wouldn't be able to find a CPU core to run a new thread on. So, why do this instead of just showing zero usage? Well, there are two main reasons.
So, if System Idle Process is taking up 99 percent of your CPU's time, this means that your CPU is only using one percent of its processing capability to run actual tasks.
The System Idle Process is, as the name suggests, just a measure of how much free processor time your computer currently has. So, what's going on, is your computer affected by malware, or is it just burning itself out for no reason? It's nothing to worry about In particular, you may notice that there's a task called System Idle Process, which can be taking anything up to 99 percent of your CPU's time. Windows Task Manager is a brilliant way to see what's going on with your computer, but it's also a little scary to see what's eating up your system resources.
