Environment

Operating System

Windows 11, 64-bit*, Windows® 10, 64-bit*
Intel® Optane™ Memory

Description

After installation of the Intel RST 16.7 version of the driver, there is no longer an option to pin files to Intel Optane memory in Windows Explorer*.

Resolution

This is expected behavior.  An issue was found in the Intel® RST version 16.7 driver/applications that results in an increase in the CPU utilization by the Windows File Explorer*.

it was root caused to be related to the Intel® Optane™ Memory Pinning Explorer Extensions, which when installed, enables pinning through Windows File Explorer.

These extensions were removed from the default Intel® RST 16.7 driver package installation to mitigate the impact from this issue.

Note
  • If the system previously contained the Intel® RST driver/application version 16.5, the extensions will remain present on the system when upgrading to the 16.7 version and this issue will continue to affect them.
    • The Intel Optane Pinning Explorer Extensions can be removed manually from the system (Win+X -> Apps and Features).
  • Pinning through the application isn't impacted.

If you still wish to use the pinning capability in the Windows File Explorer, it is best to update to the latest supported drivers and software (version 16.8.3).
