TPMAPI_E_TPM_COMMAND_ERROR

TPMAPI_E_TPM_COMMAND_ERROR is a Windows TPM API result. It indicates that the TPM itself returned a result the API did not expect for the submitted command.

What to check for TPMAPI_E_TPM_COMMAND_ERROR

  • Capture the command context and any raw TPM or TBS status available from the caller.
  • Check TPM provisioning, ownership, firmware state, and policy requirements for the requested command.
  • Avoid treating this as a generic success retry; the same command may fail until its preconditions change.
