secure boot

A class of pre‑OS attacks that tampers with the boot chain and even replaces trusted boot components — sometimes as seemingly innocent as a boot logo or signed EFI binary — has resurfaced as a practical threat to both Windows and Linux devices, and recent public disclosures show how a single...

Microsoft’s recent, subtle documentation adjustments have quietly hardened the gate for Windows 11 installations: the platform’s hardware-rooted security stack—most notably TPM 2.0, UEFI/Secure Boot, and a properly configured Windows Recovery Environment (WinRE) with PCR7 binding—has moved from...

Hi I am attempting to upgrade to the latest version 25H2. Currently, I am running version 24H2. My issue is with secure boot. When the CSM is disabled and Secure Boot enabled, it won't boot. It returns to the BIOS screen. Other wise works fine. When running the upgrade health check, secure...

Microsoft has issued another high‑visibility reminder to Windows 10 users as the operating system reaches its planned end of support, urging migrations, outlining a limited Extended Security Updates (ESU) bridge, and prompting renewed discussion about security, hardware compatibility, and...

Microsoft’s published GPO approach for rolling out Secure Boot certificate updates gives domain administrators a single, auditable toggle to opt fleets into the OS‑driven Secure Boot key rollout — but it also bundles irreversible firmware changes, telemetry trade‑offs, and a strong dependency on...

With Windows 10 reaching end of support and Windows 11’s hardware baseline enforced across upgrades and some modern games, checking whether Secure Boot is enabled — and enabling it correctly if it isn’t — has moved from optional housekeeping to an essential step for many PC owners and gamers...

Secure Boot is a firmware-level guardrail that prevents unsigned or tampered boot components from running, and checking whether it’s enabled — and turning it on safely — is a small set of Windows checks plus careful UEFI (BIOS) changes when required. Background / Overview Secure Boot is part of...

The debate over Secure Boot, TPMs, and the architecture of modern personal computers has moved from niche mailing lists into mainstream headlines — and for good reason: what began as firmware-level protections against sophisticated attacks now shapes who can run which operating systems, how...

Windows 11’s hardware rules looked like a slap in the face to users with perfectly functional PCs—until you step back and consider what Microsoft was trying to buy with that pain: a cleaner, more secure, and more future-ready base for the entire Windows ecosystem. Background When Microsoft...

EFI is the small, pre‑OS layer that brings your PC hardware to life and hands control to Windows, replacing the decades‑old BIOS with a faster, more secure, and far more flexible pre‑boot environment that modern Windows installs require. Background / Overview The Extensible Firmware Interface...

Microsoft’s decision to draw the curtain on Windows 10 has finally arrived: the decade‑old operating system has moved from mainstream support into retirement, forcing households, small businesses and enterprise IT teams into a narrow planning window where choices are security‑driven and...

Microsoft’s Secure Boot certificate rotation is no routine patch — it is a coordinated, firmware‑adjacent program that replaces the 2011 signing certificates with a 2023 family of CAs, installs a new boot manager signed by that chain, and (optionally) applies revocations and Secure Version...

Fourteen years after Windows 10 first shipped and exactly on schedule, Microsoft pulled the plug on mainstream support for Windows 10 on October 14, 2025 — and that has a lot of users suddenly asking whether their machines can actually be upgraded to Windows 11 despite a “This PC can’t run...

The discovery and public disclosure of CVE‑2025‑47827 — a Secure Boot bypass in IGEL OS versions before 11 — has forced a re‑examination of how the boot‑time trust chain is implemented in thin‑client deployments, and it has produced immediate operational consequences for administrators who still...

Microsoft has stopped providing routine security updates and standard support for Windows 10 as of October 14, 2025, creating an immediate exposure window for any PC that remains on the platform without enrollment in Microsoft’s Extended Security Updates (ESU) programme. Background Windows 10...

Microsoft has added a new enterprise-friendly way to apply the Secure Boot certificate rollout: a Windows Configuration System (WinCS) command‑line interface that lets domain administrators query and apply a predefined Secure Boot configuration key — making the complex Secure Boot certificate...

Microsoft’s new Windows Configuration System (WinCS) support for Secure Boot gives domain administrators a third, scripted path to apply Microsoft’s Secure Boot certificate updates at scale — a pragmatic addition to the existing Windows Update and manual firmware-update approaches, but one that...

Microsoft has published explicit registry controls that let IT teams trigger, monitor, and manage the rollout of the new Secure Boot certificates and boot manager signed by the 2023 Microsoft UEFI certificate family — a critical operational path for enterprises that must replace expiring...

Microsoft’s Secure Boot certificate rollover is a platform-level change that will touch firmware, OS servicing, BitLocker, and recovery processes — and IT teams must treat it as a multi-quarter program, not a routine patch. The company’s managed update flow uses a scheduled Windows task that...

Activision says the Black Ops 7 beta delivered a meaningful drop in cheating, with Team RICOCHET reporting that nearly 99% of matches were cheater‑free by the end of the beta — a result the company frames as the strongest beta anti‑cheat performance in Call of Duty history. Background Call of...
