Windows 11 KB5079473 is not causing BSODs or an inaccessible C: drive and app failures, says Microsoft

The March 2026 Patch Tuesday update, KB5079473, is not causing significant issues like BSODs or reboot loops, according to Microsoft. Reports of an inaccessible C: drive and application malfunctions on Samsung PCs are linked to a recent update of the Galaxy Connect app, not the Windows update. Microsoft confirmed no known connections between the March update and major system failures. The update includes over a dozen security fixes and introduces new features, such as improvements to the File Explorer search bar and a Bing-based Internet speed test tool. Specific Samsung models are experiencing C drive accessibility issues due to the Galaxy Connect app, which has disrupted permissions.
Microsoft's Secure Boot certificates expire in June 2026, but older PCs may never get the fix

Microsoft’s Secure Boot certificates expire in June 2026, but older PCs may never get the fix

Every Secure Boot-enabled Windows PC relies on cryptographic certificates issued by Microsoft in 2011, embedded in the motherboard's firmware, to ensure a secure boot process. The first of these certificates will expire on June 24, 2026, which will affect the ability to receive future security updates for critical components of the Windows startup process. Microsoft is rolling out replacement certificates through Windows Update, marking a significant security maintenance effort. Secure Boot operates as a chain of trust with certificates stored in the motherboard's UEFI firmware, validating software before the operating system loads. The Platform Key (PK) is at the top of this chain, followed by the Key Exchange Key (KEK) and the Signature Database (DB). The replacement certificates introduced in 2023 restructure certificate management, separating responsibilities among different certificate authorities to enhance the trust model. Not all PCs are affected by the upcoming expiration; newer devices manufactured since 2024 already have the new certificates. Windows 10 users face challenges as support for this version ends in October 2025, and they will not receive the new certificates unless enrolled in Extended Security Updates. Home users should ensure their PCs are set to receive updates automatically, while enterprise environments require coordination for firmware updates before the Windows certificate update.

Microsoft’s Secure Boot certificates expire in June 2026, but older PCs may never get the fix

Every Secure Boot-enabled Windows PC relies on cryptographic certificates issued by Microsoft in 2011 for boot process integrity. The first of these certificates will expire on June 24, 2026, impacting the ability to receive future security updates. Microsoft is rolling out replacement certificates through Windows Update, requiring collaboration between Microsoft, PC manufacturers, and users. Three critical certificates will expire: the Microsoft Corporation KEK CA 2011 and Microsoft UEFI CA 2011 in June 2026, and the Microsoft Windows Production PCA 2011 in October 2026. The new certificates introduced in 2023 have a restructured functionality to enhance security. Not all PCs are affected; newer devices manufactured since 2024 come with the new certificates. Windows 10 users face challenges as support ends in October 2025, and unsupported devices will not receive updates. Home users should ensure automatic Windows updates and check for firmware updates, while enterprise environments must verify firmware updates before applying certificate updates. The first certificate expiration is on June 27, 2026.

FRANK OS 1.0 Launches With a Retro Windows 95-Like Desktop

FRANK OS is a newly launched open-source graphical desktop operating system specifically designed for microcontrollers, with its first official version, 1.0, now available. It is built on FreeRTOS rather than the Linux kernel, optimized for the RP2350 microcontroller, which has approximately 520 KB of SRAM and dual CPU cores. The operating system features a desktop environment reminiscent of Windows 95, including overlapping windows, a taskbar, and a start-menu-style launcher. It supports standard desktop behaviors and allows users to switch between applications using an Alt+Tab-style interface. FRANK OS comes preloaded with nine lightweight applications, such as an interactive terminal, a C compiler, classic games, and a ZX Spectrum emulator. Programs can be compiled as ARM ELF binaries and loaded from an SD card. The system is aimed at hobbyists and experimental use.

Windows Server finally gets ReFS boot support

Microsoft has introduced boot support for the Resilient File System (ReFS) in Windows Server, allowing insiders to boot the server operating system directly from a ReFS volume. This feature has been made available in the latest Windows Server Insider Preview build after a fourteen-year wait since ReFS was launched in 2012. ReFS can detect corruption early and address issues online, eliminating the need for chkdsk, and supports volumes up to 35 petabytes. It also includes block cloning and sparse provisioning technologies for efficient file management. To use ReFS boot, organizations must install the latest Windows Server vNext Insider Preview with a minimum build number of 29531.1000.260206-1841, format the system partition as ReFS, and ensure UEFI firmware is used.
