Microsoft released KB5064010 on August 12, 2025 — a hotpatch that updates eligible Windows 11 Enterprise LTSC 2024 and certain Windows Server Azure Edition builds to OS Build 26100.4851, delivering narrowly scoped security hardening without the usual restart required by cumulative updates...
The September cumulative for Windows 11 — KB5065426 — has left a significant number of users and administrators wrestling with failed installs, a spectrum of error codes, and in some environments, broken file and print sharing; for many affected systems the most reliable workaround so far is...
Microsoft’s September cumulative for Windows 11, KB5065426 (OS Build 26100.6584), is proving to be a high‑priority security and quality rollup — and for a meaningful subset of users it’s also proving unusually stubborn: installs failing with a wide variety of error codes, long downloads, and in...
Windows 11’s September Patch Tuesday cumulative, KB5065426 (OS Build 26100.6584), has been linked to widespread file- and print-sharing failures on some machines, with multiple community threads and Microsoft Q&A posts reporting disabled sharing settings, networks switching from Private to...
Microsoft has warned that several of the Secure Boot certificates baked into Windows devices a decade ago will begin to expire in mid‑2026, forcing a coordinated certificate rollover that every PC owner and IT team should plan for now to avoid loss of pre‑boot updates, compatibility problems...
Microsoft’s Secure Boot update FAQ makes clear that a coordinated, multi-step transition is now live: Windows will roll new 2023 signing certificates into UEFI variables and update the Windows boot manager to preserve Secure Boot protection ahead of the 2011 CA expirations, but the rollout...

Microsoft is rolling out Windows 10 Build 19045.6388 (KB5066198) to the Release Preview Channel, delivering a targeted quality rollup for devices on Windows 10, version 22H2 that focuses on reliability, enterprise scenarios, and a handful of practical fixes rather than broad consumer-facing...
Microsoft pushed the September 2025 Patch Tuesday rollup to Windows 11 today, a cumulative release that—according to community reporting—carries the usual mix of security fixes, quality improvements and targeted Copilot reliability updates, but also surfaces a handful of user-facing regressions...

Microsoft released the September 9, 2025 cumulative update for Windows 11, version 24H2 — KB5065426 (OS Build 26100.6584) — a combined security and quality rollup that both closes recent high‑priority vulnerabilities and addresses a string of functional regressions introduced earlier in the...
Microsoft released a cumulative security update today for Windows 11’s servicing branches 22621 and 22631 — published as KB5065431 (OS Builds 22621.5909 and 22631.5909) — that combines a Latest Cumulative Update (LCU) with a servicing‑stack update (SSU) and carries a set of security and quality...
Windows 11 users faced a sudden and alarming data‑integrity scare when an August cumulative update was linked to a reproducible failure mode that can make certain SSDs “vanish” from the operating system during sustained, large writes — a problem that can truncate files, corrupt partitions, and...
Last month’s Windows 11 patch KB5063878 triggered a flurry of alarm among power users and IT pros after a narrow set of SSDs began disappearing under heavy write conditions — a regression serious enough that some users experienced irrecoverable data loss. This feature walks through a practical...
Windows 11’s next annual feature update is now moving from staged preview into its final validation ring: Microsoft has made Windows 11, version 25H2 available to Release Preview Insiders and commercial customers for targeted testing, delivered as an enablement package on top of the 24H2...

Microsoft’s Windows 11, version 25H2, is deliberately low‑drama: rather than introducing a slate of brand‑new consumer features, Microsoft shipped it as a small enablement package that activates functionality already staged in the 24H2 servicing stream — and, in the process, removes legacy...
Microsoft has pushed targeted Out‑of‑Box Experience (OOBE) updates for Windows 11 in late August 2025—delivering KB5065813, KB5065847 and KB5065848—to change how new and freshly imaged devices handle day‑one servicing and enrollment during initial setup.
Background
Microsoft has been reworking...
August closed out with a busy month for Windows 11: Microsoft shipped the August Patch Tuesday rollups and an optional non‑security preview that together folded in a mix of productivity‑focused on‑device AI, UI polishing, enterprise housekeeping, and several reliability and recovery improvements...
