How readiness works. Each verdict comes from public signals only: the CVEs MSRC lists as fixed, CISA's exploited catalog, EPSS, the known issues Microsoft publishes on Windows release health, out-of-band follow-ups, and news or community posts that mention the KB. It is a starting point for your own testing, not a guarantee for your environment.
