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.
