TPMAPI_E_INVALID_CONTEXT_HANDLE
TPMAPI_E_INVALID_CONTEXT_HANDLE is a Windows TPM API result. It indicates that the supplied context handle is uninitialized, closed, corrupted, or belongs to a different operation lifetime.
What to check for TPMAPI_E_INVALID_CONTEXT_HANDLE
- Create a new context and avoid reusing handles after close, failure, or process restart.
- Ensure that a context is used only by code that owns its lifetime and synchronization.
- Check handle initialization and cleanup paths for double-close or use-after-close errors.
Microsoft documentation for TPMAPI error codes
Diagnostic interpretation
This result has the HRESULT value 0x8029010A. AllStat records the condition as “The specified context handle was not valid.”.
Evidence to capture
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions this result or the tpmapi / context / handle operation.
- check the documented return contract of the specific API because the same HRESULT can require different recovery in different interfaces.
Retry and recovery
Avoid an immediate retry loop after TPMAPI_E_INVALID_CONTEXT_HANDLE. First establish what state must change, make that narrow correction, and then repeat the same operation with the same diagnostics enabled.
