Some users report high CPU usage on their computers during ordinary activities (like Teams calls).

How can I collect a report of processes causing high CPU usage over a few hours?

I would like to use Windows 10 or sysinternals tools for this purpose.

I have read [https://serverfault.com/questions/33776/get-a-history-of-cpu-memory-usage/33789#33789] which recommends PerfMon, but Perfmon requires to add every process you need to monitor explicitly (1). I need to know what processes make heavy use of CPU.

    This seems to be answered already here: [Get a history of CPU/memory usage](https://serverfault.com/questions/33776/get-a-history-of-cpu-memory-usage) – Luuk Aug 12 '23 at 16:40
  • I read that post before posting, especially [@Matt's answer](https://serverfault.com/a/33789/967397) but I was not able to make use of it. Any tutorial about that specific data collection with _PerfMon_ or any other tool is welcome. – Christine VACHER Aug 12 '23 at 18:14
  • [This thread](https://superuser.com/questions/609529/history-of-cpu-usage-for-all-processes) contradicts [@Matt's answer](https://serverfault.com/a/33789/967397): _Perfmon requires to add every process you need to monitor explicitly_. This is not the tool for that purpose. – Christine VACHER Aug 12 '23 at 18:28

  • On superuser.com: [Log %CPU by Process over time](https://superuser.com/questions/453909/log-cpu-by-process-over-time) (It is using [procmon](https://learn.microsoft.com/en-us/sysinternals/downloads/procmon) from sysinternals) – Luuk Aug 12 '23 at 19:39
  • Thank you @Luuk for finding this post. I haven't tried _procmon_ yet, but it seems to do what I want. – Christine VACHER Aug 13 '23 at 00:00
  • @ChristineVACHER Perfmon doesn't require you to add process manually - just launch it from Task Manager or using `perfmon /res` from the command line. – Zac67 Aug 13 '23 at 11:08
