Microsoft is preparing a quiet but critical update to the foundation of Windows platform security: the Secure Boot certificates that firmware uses to validate every component that runs before the operating system. Those original Microsoft certificates issued in 2011 begin to expire in mid‑2026...

Secure Boot’s root certificates are getting a generational refresh — and the Windows ecosystem is executing one of the largest coordinated certificate rollouts in recent memory to ensure PCs keep a trusted boot chain well past June 2026. This update is not an optional security nicety: it...

Microsoft’s warning is short and stark: the Secure Boot certificates that have protected Windows boot chains since 2011 begin expiring in mid‑2026, and while most PCs will receive replacement certificates automatically, a significant minority of systems — especially managed, offline, or...

If you own a Windows PC made since 2011, your machine is part of a global certificate rollover that must complete before critical Secure Boot certificates begin expiring in mid‑2026 — and there are simple checks and concrete steps you can take today to confirm your system is ready. Background...

Microsoft and the PC industry have quietly opened a narrow but critical window to prevent a pre‑OS security gap this year: Windows will start rolling replacement Secure Boot certificates into device firmware via staged OS updates, while Microsoft is simultaneously intensifying its public push...

Microsoft is quietly rolling out a coordinated update to refresh long‑lived Secure Boot certificates because a set of Microsoft‑issued UEFI certificates from 2011 will begin expiring in 2026 — and systems that don’t receive the replacement “2023” certificate family beforehand risk losing the...

Microsofts Warnung vor ablaufenden Secure‑Boot‑Zertifikaten ist kein bloßes Wartungsthema — sie betrifft die Grundlage dessen, wie moderne Windows‑PCs und viele Sicherheits‑Ökosysteme das System‑Startverhalten verifizieren. Microsoft hat dokumentiert, dass mehrere Microsoft‑ausgestellte...

Microsoft has quietly given IT teams a new lever: a built‑in Secure Boot status report in the Intune / Windows Autopatch admin surface that lets administrators see, at device granularity, which endpoints have Secure Boot enabled, which are already carrying Microsoft’s replacement Secure Boot...

Microsoft’s management toolchain now surfaces Secure Boot readiness and certificate status inside Intune, giving IT teams a single-pane view and control points to manage the platform-level certificate rotation required before Microsoft’s legacy Secure Boot CAs begin to expire in 2026. This...

IT administrators now have practical, fleet-scale ways to check whether Windows devices are carrying the updated Secure Boot certificate chain and whether they’re ready to accept the upcoming Secure Boot updates — a crucial capability as Microsoft and OEMs rotate the platform’s cryptographic...

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...

Microsoft has begun a coordinated, multi-year hardening of Windows that moves long-standing behaviors—particularly around Kerberos/PAC validation, Netlogon, and Secure Boot certificates—into a stricter, enforcement-first posture, and IT teams must act now to avoid authentication outages, boot...

Microsoft’s KB5074110, published January 29, 2026, is a targeted Setup Dynamic Update for Windows 11 (versions 24H2 and 25H2) and Windows Server 2025 that refreshes the tiny but critical Setup runtime and related binaries — and it arrives at a delicate moment for IT teams because it also touches...

Windows 11 reaching one billion users — and doing it faster than Windows 10 — is the kind of headline that gets product teams, OEM partners, and IT departments talking. Microsoft quietly confirmed the milestone during its fiscal Q2, 2026 commentary, and company executives have since framed the...

Microsoft has released Windows 11 Insider Preview Builds 26100.7701 and 26200.7701 (packaged as KB5074105) to the Release Preview Channel, delivering a mix of targeted Copilot+ PC enhancements, platform-wide quality fixes, and a handful of noteworthy system-level changes that administrators and...

Highguard verlangt, dass Ihr System mit aktivem Secure Boot und einem bereitgestellten TPM 2.0 startet — wenn diese Voraussetzungen fehlen, verweigert das Spielstartverfahren den Start und zeigt eine entsprechende Fehlermeldung an. Viele Spieler stehen deshalb vor der Frage: Wie aktiviere ich...

Highguard’s PC launch is already stirring debate: the free‑to‑play PvP raid shooter requires platform‑level security—Secure Boot and TPM 2.0—and won’t launch unless those features are present and properly configured. That requirement is driven by the game’s use of kernel‑level anti‑cheat (Easy...

Microsoft pushed a string of Windows updates over the weekend that try to clean up several regressions introduced by the January Patch Tuesday rollouts — and at the same time have started a phased, OS-driven refresh of Windows' Secure Boot certificates that will touch millions of devices ahead...
