During validation, an issue was encountered in the Intel® RST version 16.7 driver/applications. This results in the system staying in C0 and not able to enter C10 core idle power state. This could also result in an increase in Windows* File Explorer CPU utilization.
This is related to the Intel® Optane™ Memory Pinning Explorer Extensions, which when installed, enables pinning through Windows* File Explorer.
To mitigate the impact of this issue, these extensions were removed from the default installation with the Intel® RST 16.7 driver package on a clean OS installation.
If you wish to still use the pinning capability in the Windows File Explorer, it is best to update to the latest drivers and software (version 17.x or later).
