Microsoft – Windows – Performance Tools – Kernrate ( Use Case – Intelppm )

Found out that intelppm.sys was using Kernel the most.

I ran around trying to find a newer driver for it.  But, really could not.

Thank goodness for that, as it allowed to dig a big deeper into Intelppm.sys.

Found out that it is part of “Energy Saver” commitment from Intel.

If you absolutely do not want it on and you have already taken other measures:

Then to turn it off intelppm. sys do the following:

rem disable intelppm service, so that it no longer
rem starts "on-demand"
sc config intelppm start= disabled

rem stop any current run
sc stop intelppm

Please note that there are other “Processor Device Drivers” that serve similar functionalities:

  • AMDK8.sys
  • p3.sys
