The issue you’re experiencing with Process Explorer might be due to a few reasons:
Differences in CPU Usage Calculation: Process Explorer might calculate CPU usage differently than other tools like Task Manager1. This could result in discrepancies in the reported CPU usage.
Disk Input/output (I/O): If your system is experiencing high disk I/O, it might appear as though the CPU usage is low when in fact the system is being slowed down by disk operations.
Software Compatibility: There might be compatibility issues with Process Explorer and your version of Windows.
Administrative Privileges: Running Process Explorer as an administrator might affect the way it displays CPU usage.
If the CPU Usage column is blank, it might be worth checking if there’s an update available for Process Explorer
