I downloaded latest official win11 media from ms and tried to use them to initialize a hyper v vm. However, I cannot boot into installation without disabling secure boot in VM settings. Many thanks in advance for any assistance Joe

Microsoft has quietly begun rolling out replacement Secure Boot certificates to Windows PCs to prevent a calendar-driven failure when long‑running Microsoft UEFI certificates issued in 2011 begin to expire this June; the changes are being delivered through January 2026 cumulative updates...

Microsoft released the January 13, 2026 security baseline today — published as KB5074109 — and enterprise administrators should treat this as both a mandatory security checkpoint and a practical reminder about the new Hotpatch servicing cadence for Windows 11 Enterprise (24H2 and 25H2). The...

Microsoft has started an automated, phased replacement of expiring Secure Boot certificates on eligible Windows 11 systems, a preventative move to avoid widespread boot‑level serviceability and security loss when long‑running Microsoft certificates issued circa 2011 begin to expire in mid‑2026...

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...

The long-lived ATI Radeon HD 2600 XT — a midrange 2007–2008 GPU that shipped in dozens of retail and OEM boards and even as an Apple‑blessed option for early Mac Pro systems — can still be made to work on modern Windows systems, but the path is now one of compromise: you can expect a stable...

Microsoft’s first security update for Windows 10 in 2026, KB5073724, is a compact but consequential patch: it’s a security-only cumulative for Extended Security Update (ESU) and LTSC devices that removes legacy modem drivers, prepares devices for Microsoft’s replacement Secure Boot certificates...

Microsoft’s January cumulative for Windows 10 — KB5073724 — arrived as a focused security rollup that changes how some legacy hardware is supported and begins a careful, OS‑side rollout of replacement Secure Boot certificates ahead of 2026 expirations, while also packaging a batch of important...

Microsoft’s Secure Boot trust anchors — the firmware‑provisioned certificates that validate bootloaders and the Windows boot manager — are approaching end‑of‑life, and the coordinated replacement process introduced by Microsoft and OEMs is now the single most urgent operational task for Windows...

December’s Windows updates closed the year with a steady stream of practical improvements for enterprise administrators, security teams, and endpoint managers — from a major Secure Boot readiness campaign to storage and encryption upgrades that promise measurable performance and security gains...

I stopped carrying a handful of dedicated installer sticks the moment I discovered a working Ventoy drive: install Ventoy once, copy ISO/WIM/IMG/VHD(x)/EFI files like ordinary files to the drive, and boot whichever image you need from a tidy menu. This simple architectural shift converts a USB...

Windows 11 can be installed on many PCs that Microsoft labels “unsupported,” but doing so is a trade-off: several reliable community methods exist to bypass TPM, Secure Boot, and CPU checks — including a registry override, Rufus’s extended installer, replacing compatibility files like...

When Secure Boot is supposed to be the safety net that stops unsigned code from running before the operating system, a small logic shortcut in the firmware can erase that protection — and that is precisely what the newly published CVE-2025-2296 describes: an EDK2/OvmfPkg flaw that can let a...

Microsoft’s Secure Boot certificate rollover is a single operational item that can break trust across your fleet if it is ignored — Intune offers a manageable path to deploy the replacement 2023 Secure Boot certificates, but it must be used deliberately: inventory first, pilot widely, coordinate...

Canonical's security team has disclosed CVE-2025-2486, a firmware-level issue in Ubuntu's edk2 packages that left the UEFI Shell accessible inside AAVMF (the ARM64 QEMU UEFI binary) even when Secure Boot was enabled — a configuration that can permit Secure Boot bypasses in affected virtualized...

Microsoft has opened the conversation: an Ask Microsoft Anything (AMA) session on December 10 will walk IT teams through the new Secure Boot playbook and the practical steps required to update expiring Secure Boot certificates before they begin to lapse in June 2026. The conversation matters...
