Hi, I've just switched to a new Windows 11 system and installed Process Explorer. I'm running it as an administrator and it seems to display all processes properly but is showing significantly lower CPU usage than Task Manager. Process Explorer says that I have 14 cores and 20 logical processors but I don't know if that's a factor.
