WER_S_IGNORE_ALL_ASSERTS

WER handled the assertion and added it to a permanent ignore list

WER_S_IGNORE_ALL_ASSERTS is HRESULT 1769481 (0x001B0009) from winerror.h. The documented description is “The assertion was handled and added to a permanent ignore list.” In the Windows Error Reporting collection, queue, upload, archive, assertion, or debugging workflow, the value reports a nonfailure state that must not be collapsed into plain S_OK.

This result is actionable completion information and may require waiting, reconciliation, fallback, or user disclosure.

Where the status is encountered

  • WerReportSubmit and WER store processing; capture the exact API, object, and phase because the same numeric success severity does not define the state by itself.
  • Crash, hang, assertion, and application-failure reporting;
  • Enterprise policy controlling WER queue, archive, upload, debugger, and throttling;

What must be true before accepting it

Verify that the broad ignore decision is authorized and scoped to the correct assertion identity and application version. The caller should reject a path where outputs and state do not match the recorded condition.

Correct handling and recovery

Record the ignore rule, provide a way to remove it, and avoid hiding unrelated assertion sites that share a generic message.

Continuation after it within the documented state machine is different from restarting the entire operation.

Difference from nearby results

The instance-only variant resumes once; this status changes handling for future matching assertions.

Practical scenario

A developer suppresses a noisy assertion fingerprint for one build. The tool stores the exact module and line signature and expires the rule on upgrade.
