Q: High CPU usage by system process after 5 minutes being idle

Raffaele D'ArcoWhen I'm idle (I'm stuck on the desktop) after 5 minutes, I can see a high CPU use from the system process. See the following screen from Process Explorer as an example. As you can see I'm running Windows 10. How can I fix the problem?

you likely have the idle maintenance scheduled task that runs and scans your RAM for error. Check my answer and look for ntoskrnl.exe!RtlpGenericRandomPatternWorker, ntoskrnl.exe!RtlpTestMemoryRandomUp calls in callstack of system process.

@magicandre1981in my case this is the process ntoskrnl.exe kistartsystemthread
@magicandre1981 This only occurs when it is connected to the electric current

you have no expanded the stack correctly. share the ETL file (compressed as 7z) so that I can take a look at it

The file is 500MB because the process start after 5 minutes. So i expand computation/cpu usage (sampled). Then?
OK this is the screen correctly ibb.co/h3qv7v But why is 1.20 in total? CPU is 18% when start system process....
The downlad of the file is dropbox.com/s/qdq20q7iycc5oru/cpu%20usage.rar?dl=0 54MB

looking at the picture shows exactly what I told you. I see the ntoskrnl.exe!RtlpGenericRandomPatternWorker call, so the memory test during idle maintenance. so disable this task to fix it

Hi magicandre1981
this is the task? RunFullMemoryDiagnostic?
and ProcessDiagnosticEvents?
I have disabled those two tasks but now I have the problem of using the 100%
Is it the silentcleanup task?
