June Windows 11 sécurité updates now double as a Secure Boot readiness rollout
Microsoft says KB5094126 addresses the June 2026 sécurité vulnerabilities pour Windows 11 24H2 et 25H2 pendant also adding higher-confidence targeting so more éligible devices can automatically receive the newer Secure Boot certificates ahead of the 2026 expiry window.
Endpoint teams need to treat the June deployment as both patch remédiation et boot-trust maintenance, avec ring validation focused on certificate delivery, restart health et deployment-media dependencies instead of stopping at CVE closure alone.
