Windows 11 (24h2) running on Dell XPS 8940, i7-11700 cpu. I have gone thru all the diagnostic steps I could find, results are clean boot doesn't change usage, only mode that "calms" the cpu usage is safe mode

I have attached image showing Process Explorer, note the 3 threads running at 6+% apiece.

Any theories? (I have also posted this in support, no replies, so trying here)

And the problem is what? There are processes running in the background so unless the computer is turned off there will always be some indication of running just like a car engine at a stoplight.

I have, and have worked on, many windows 10 and 11 systems. It is NOT normal for an idle system to have a process running at 18% cpu usage. Check the image, there are three unidentified threads in the ntoskrnl.exe (alias System) process, each running at 6%. I can leave the sysem on indefinitely, the 3 threads never go away, and stay constant at the 6% usage each.

Since nobody has a sensible theory, perhaps someone can give me information on how to step thru the startup process and find what startup service is spawning the three threads via ntoskrnl.exe. Again, disabling all of the non-Microsoft processes (clean boot) does not cure the problem, and booting into safe mode does. So my assumption is there is a Microsoft service interacting with ntoskrnl.exe that fires off these three permament threads that use 18% of my cpu capability.

I have done numerous stress tests on the cpus and memory, no errors apparent. SFC and DISM both indicate a clean system. I've spent hours on the Internet looking for a clue, no help. I was hoping somebody in this group could aim me so that I can dig out the answer.

Wow HASP, I didn't think anyone used that anymore.

A side note: A tool I use on my personal computers is a debloater by Chris Titus (https://christitus.com/windows-tool/) It clears out a lot of useless stuff.

Interesting, what are the thread names?
