when pc is idle for app 4 minutes, process starts taking app 25 % (one core) of CPU.
I have driver talent for update, I tried several windows 10 healing opetions.. but still remains. Malware scanned as well..

5My suggestion is to stop using third-party software to update drivers. Unless there is a problem a device driver should not be updated unless its a GPU. If it is a GPU driver update just get it from AMD/Nvidia/Intel directly.– RamhoundOct 16, 2015 at 16:25

What problem do you think the WDK is going to solve exactly? If you are not specific we can't tell you where to find the driver for the device.– RamhoundOct 16, 2015 at 16:40

I just have seen articles about it.– DavidOct 16, 2015 at 16:43

Be specific what articles?– RamhoundOct 16, 2015 at 16:44

capture a xperf trace of the CPU usage. First Install the WPT which is part of the Windows 10 SDK. Now open a cmd.exe as admin and run this command to capture 30s of the CPU usage:
xperf -on latency -stackwalk profile -buffersize 2048 -MaxFile 2048 -FileMode Circular && timeout 30 && xperf -d C:\HighCPUUsage.etl
Open the trace in WPA.exe, load the debug symbols from the Microsoft symbol server.
Now Drag & drop the CPU usage (Sampled) graph to the right side of WPA and choice this layout and extand the stack of the SYSTEM Process and look where the CPU usage splits:
(in this demo, the Kernel is busy zeroing the RAM).
Now you should see the cause. If you need help, share the compressed ETL file so that I can take a look at it.

@David have you tried it? Do you see what causes the CPU usage? Nov 3, 2015 at 18:23
