TPM_E_PCP_INTERNAL_ERROR
TPM_E_PCP_INTERNAL_ERROR is an unexpected internal failure in the Microsoft Platform Crypto Provider. It does not identify a specific key, policy, or TPM command problem by itself.
What to check
- Capture TPM state and provider logs before resetting anything.
- Retry once after normal system conditions are restored; if the failure persists, collect TPM logs and compare firmware/BIOS versions across affected devices.
- Keep the original inner error and event-log records, because they are more actionable than the generic PCP wrapper status.
