STATUS_INVALID_PEP_INFO_VERSION

The plug-in side of the PoFx registration contract has the wrong version

STATUS_INVALID_PEP_INFO_VERSION is specifically tied to the version of PEP_INFORMATION supplied during Platform Extension Plug-in registration. Microsoft documents this return from PoFxRegisterPlugin when PEP_INFORMATION.Version is invalid. It should be separated from STATUS_INVALID_KERNEL_INFO_VERSION, which concerns the kernel-information structure in the same registration relationship.

PEP_INFORMATION carries the PEP's notification callbacks and version data. The structure is part of a versioned interface between the platform plug-in and PoFx. An incorrect version can result from mismatched headers, stale private copies of WDK definitions, or a wrapper that initializes the wrong structure revision.

What to inspect

  • The exact PEP_INFORMATION definition compiled into the failing PEP.
  • The Version value and callback table supplied to PoFxRegisterPlugin or its extended form.
  • Build/deployment mixing between the PEP binary and platform support components.
  • Any compatibility layer that serializes or copies the registration structure.

Do not infer a device power-policy failure from this status; registration has not established a valid PEP interface. Fix the structure contract first, then investigate device notifications or power-state behavior only after PoFx accepts the plug-in.
