Windows 10: System process jumps to 25% after being idle.

Heya,

I have an old gaming PC that I now use to run small sized game servers for friends or idle in certain games.

Recently the system process has started jumping to 25% and staying there after the computer has been idle for 5 minutes. Normally not an issue however the fans are quite loud.

I tried to see what was happening in process explorer but expanding the System process didnt show anything.

However I did notice the process "taskhostw.exe", in the red box, will immediately terminate if I do anything (once the systems no longer considered idle) and the CPU usage will return to normal.

Here is the screenshot.






I know the usual suspect is windows update but I've noticed that starts up under "svchost.exe (netsvc -p)", so seems to be a different issue but I could be wrong of course and that's why im here!

It's running Windows 10 1903.

Anyone know how I can solve this?

:)

 

System Idle Process CPU Allocation?

Hi,

I am Sumit, an Independent advisor and a Microsoft MVP here to help.

System Idle Process, as the name suggests is a process that indicates CPU is idle and is not being used, aka is at rest. This is done to totalize CPU usage to 100 between the processes.

So you do not have to worry about anything.

System Idle Process

System idle process should show "99" if your computer is idling. If it's only showing 50 then some other process is eating up your other 50, find it and sic your antivirus on it.
