Microsoft has notified the Windows ecosystem of a far-reaching, time‑bound change: the Secure Boot certificates that Microsoft issued around 2011 will begin expiring in mid‑2026, and a coordinated replacement (the 2023 certificate family) is being delivered now to prevent a calendar‑driven...

Microsoft's original Secure Boot certificates—the cryptographic anchors that validate everything that runs before Windows—are entering a hard operational deadline that will force Windows Server administrators to act now: certificates issued around 2011 begin expiring in June 2026, and servers...

Microsoft has quietly begun a platform-level refresh of the cryptographic anchors that protect Windows’ pre‑boot environment, delivering new Secure Boot certificates through Windows Update and coordinated OEM firmware work to head off a calendar‑driven failure when Microsoft’s original UEFI...

An authentication bypass in GRUB2 tracked as CVE-2023-4001 lets an attacker with physical access to a machine defeat GRUB’s boot-time password protection by tricking the bootloader into loading a configuration that doesn’t contain the password settings. The defect arises from how GRUB searches...

Microsoft has quietly started the work that will prevent a class of very old Secure Boot signing certificates — the ones first shipped in 2011 — from being usable after they expire between June and October 2026, and that work matters for anyone who cares about boot‑time integrity on Windows...

Microsoft’s warning that the Secure Boot certificates issued during the Windows 8 era are being retired in 2026 is not a hypothetical maintenance note—it’s a scheduled refresh of the cryptographic trust anchors that run before Windows even starts, and it has meaningful operational and security...

Microsoft has issued a coordinated warning: the original Secure Boot certificates that have underpinned Windows platform integrity since 2011 are reaching the end of their lifecycle, and a deliberate, ecosystem-wide refresh is required before mid‑2026 to avoid a progressive loss of...

Microsoft’s timeline for the Secure Boot certificate refresh has moved from advance warning to an operational deadline: the long‑running Microsoft Secure Boot trust anchors issued in 2011 begin to expire in mid‑2026, and while Microsoft and OEMs have already built and started shipping a...

Microsoft has quietly sounded the alarm: the Secure Boot certificates that underpin the Windows platform’s pre-boot trust model are reaching the end of their planned lifespan this year, and organizations and consumers alike need to act now to avoid degraded boot security, compatibility problems...

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 and PC OEMs are coordinating a broad, time‑sensitive replacement of the Secure Boot certificates first deployed in 2011 — the original Microsoft UEFI/KEK/PCA certificates begin expiring in June 2026 (with a remaining production PCA following later in 2026). Microsoft has issued a...

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...

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 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...

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...

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...

Microsoft quietly pulled the standalone Windows 10 security update KB4524244 after users and administrators reported installation failures, system freezes, and broken recovery paths, exposing a rare but serious problem: a security patch designed to protect the UEFI Secure Boot environment can...

Pocket‑lint’s short, practical checklist for speeding up Windows 11’s File Explorer is the kind of hands‑on guidance that saves time and frustration: clear Explorer caches, turn off Quick Access, tame indexing, apply a targeted Registry tweak to stop folder sniffing, and—if you still need...

Alejandro Armas — known on GitHub as mycroftsnm — has released a compact collection of five boot-time UEFI games that force a simple choice every time you start a PC: win, and the machine continues to boot; lose, and it shuts down. The project, published as the UEFIGame repository, bundles a mix...
