The memory diagnostics results can be viewed in Event Viewer after the test completes and Windows returns to the desktop.
Use this path in Event Viewer:
- Open Event Viewer.
- Go to Event Viewer (Local) > Application and Services Logs > Microsoft > Windows > MemoryDiagnostics-Results > Debug.
- In the results pane, select a message to view the details of that memory test run.
A successful no-error result is indicated by Event ID 2001, which means no memory errors were detected.
Based on the described behavior, the results were not visible until the test fully completed and Windows resumed normally after the required recovery PIN step. After that, the event log entry and notification appeared, which is consistent with the results being available only after the diagnostic run finishes and the system returns to Windows.
