Delivered Windows Event Log Receiver SID Resolution feature for the opentelemetry-collector-contrib project, enabling automatic resolution of Windows SIDs to user/group names via the Windows LSA API. This improves log readability and accelerates security investigations. The change includes end-to-end enrichment tests, cache and SID-mapping tests, and platform-specific build checks. Documentation updated (README.md, testdata README.md, and testdata collector-config-example.yaml) with usage, defaults, benchmarks, troubleshooting, and well-known SIDs reference. Linked to tracking issue Fixes #45875. Repository: open-telemetry/opentelemetry-collector-contrib. This work increases operator efficiency, reduces mean time to detect/respond (MTTD/MTTR), and enhances overall security observability.
