Recently my fan has been a little louder than it usually is and I wasn't sure why until I looked at the CPU usage which is always around 10-20% during idle.

My computer has been running Windows 8.1 for couple months now with out many issues. I uninstalled some of the newer programs I installed thinking it might of been something new but the problem persists.

I've read various places trying

  • Stopping Intel PROSet monitoring service (not installed)
  • Disabling plugins in Chrome
  • Running an SSD so don't need to defrag
  • Tried some various integrity checks found online.

I've been trying to use the resource monitor in Windows 8 to identify the problem but am not sure what I should be looking for. See below for a picture of my processes:

I know this is a specific program to my computer but can someone help me how to diagnose what is eating all the CPU?

I have the dump but its 26megs, I could post it to dropbox but isn't there sensitive info in the .etl file – Nick Jan 14 '14 at 17:20
I see no content, only the names. Post a dropbox link here. – magicandre1981 Jan 14 '14 at 17:48
The kernel.etl is useless. I need the HighCPUUsage.etl which is generated inside the folder where you started the CMD. Look inside System32. Please also compress it (zip,RAR, 7z). – magicandre1981 Jan 15 '14 at 5:00

You don't have any high CPU usage caused by Service Host (svchost.exe). The high CPU usage comes from starting and stopping of the sdclt.exe every second. This is a known bug in Windows 8.1 when you do an upgrade from 8.0 to 8.1.

The solution to reduce the CPU usage is to stop and disable the ConfigNotification task in the Windows Task Scheduler:

Task Scheduler->Microsoft->Windows->WindowsBackup

Awesome, Cpu is back to idling around 0%. Thanks!! – Nick Jan 15 '14 at 18:23
Do you happen to know if there are any side effects? For example, would this cause Windows Backup to fail? – Bob Jan 16 '14 at 5:03
@Bob In 8.1 the Windows Backup is removed. Only the full systembackup is still included. This task is only the notification that Backup is not configured. – magicandre1981 Jan 16 '14 at 5:05
@magicandre1981 Ah, ok. So it's perfectly safe. (Huh, didn't know they removed that. I guess it's a good thing.) – Bob Jan 16 '14 at 5:07
