Microsoft’s latest round of security hardening is not subtle: it changes core authentication flows, removes long‑standing legacy protocols, and tightens boot and installer behavior in ways that are already breaking devices, apps, and fleet workflows in the wild. These updates are deliberate and...

Microsoft’s long-lived Secure Boot certificates issued around 2011 are scheduled to begin expiring in mid‑2026, and the operating-system and firmware ecosystem is in active, coordinated motion to replace those keys with a new “2023” certificate family to avoid a calendar-driven break in Secure...
