secure boot

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...

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...

Secure Boot stops unsigned or tampered code from running before Windows loads, and enabling it on a Windows 11 PC is one of the highest‑impact security steps you can takeye — but it must be done in the right order with careful preparation to avoid data loss or BitLocker lockouts. Background /...

Microsoft is holding a second Ask Microsoft Anything (AMA) focused on the Secure Boot certificate update campaign on February 5 — an event aimed squarely at IT teams, security engineers, and device managers who need to prepare Windows devices for the retirement of legacy Secure Boot certificate...

Microsoft released a targeted security rollup for Windows 10 on January 13, 2026 — KB5073724 — and is asking eligible systems to take it seriously: the update prepares devices for an imminent Secure Boot certificate renewal, removes four legacy in‑box modem drivers that carry high‑risk baggage...

Microsoft’s January Patch Tuesday includes a narrowly targeted but high‑impact fix that refreshes expiring Secure Boot certificates on Windows devices — a preventive update that closes a small window attackers could use to install persistent bootkits before the operating system loads. The...

Microsoft’s January Patch Tuesday includes a high-priority update that refreshes expiring Secure Boot certificates on Windows devices — a preventative, must-install fix that closes a narrow but critical window attackers could use to install persistent bootkits before the OS loads. rview UEFI...
