Microsoft’s August cumulative for Windows 11 — released as KB5063878 (OS Build 26100.4946) — is now at the center of a rapidly developing reliability story: independent testers and multiple tech outlets report that, under sustained large writes (commonly cited around 50 GB and above), some NVMe...

Microsoft’s latest Windows 11 cumulative update has been linked by multiple community tests and vendor advisories to a storage regression that, under specific conditions, can make some NVMe SSDs disappear during large sustained writes — risking data corruption or loss — and has reignited a...
Microsoft’s August cumulative (KB5063878) is making some SSDs and HDDs vanish mid‑write, and a patchwork of community testing, vendor responses and cautious guidance now makes a compelling case for pausing non‑urgent Windows updates and treating large, continuous file transfers as high‑risk...

Microsoft’s August cumulative for Windows 11 (the KB5063878 rollup, OS Build 26100.4946) has been linked by independent testers and enthusiast outlets to a storage regression that can make some SSDs temporarily — and in a minority of cases permanently — disappear during sustained large writes...

Phison has publicly acknowledged that two recent Windows 11 security updates — KB5063878 and KB5062660 — are associated with a cluster of SSD failures that make drives vanish during large, sustained write operations, and the admission has sparked urgent questions about update testing, firmware...
Microsoft’s August cumulative for Windows 11 has left a trail of disrupted installs and disappearing NVMe drives, and Phison — maker of widely used SSD controllers including the PS5012‑E12 — has confirmed it is investigating reports that the updates KB5063878 and KB5062660 can trigger...
The latest Windows cumulative update has landed with a thud: a growing number of users report that Windows 11 version 24H2’s August security rollup (KB5063878, OS Build 26100.4946) can make drives disappear under heavy I/O, and the fallout has reignited debates about privacy, platform stability...
Microsoft’s August cumulative for Windows 11 24H2 (KB5063878) has been tied to reports that, under specific heavy-write conditions, some NVMe SSDs — particularly Phison-controller models — and a small number of HDDs can become inaccessible and in some cases suffer file corruption, prompting...

I’ve been putting off the full switch to Windows 11 — and I’m not alone: recent developments from Microsoft have made it rational for many users to stay on Windows 10 for now. The vendor’s rollout of a consumer Extended Security Updates (ESU) option, growing reports of performance and stability...

Microsoft’s August cumulative for Windows 11 (KB5063878) is at the center of a growing, technically consistent set of community reports: after installing the update, some users say NVMe SSDs can “vanish” during large, sustained file writes — sometimes leaving files corrupted, SMART/controller...

Microsoft's brief on the hardware floor for running Android apps on Windows 11 boils down to a simple, pragmatic message: you need a modern PC — preferably with an SSD, virtualization enabled, and at least 8 GB of RAM (16 GB recommended) — and even then the practical value of that capability is...

Microsoft’s latest cumulative for Windows 11 24H2 has been tied to a small but serious cluster of storage failures that can make NVMe SSDs disappear during heavy writes and, in a handful of cases, leave data unreadable — a scare that underscores why updating and backup discipline still matters...
Microsoft’s August cumulative for Windows 11 (KB5063878, OS Build 26100.4946) shipped with security fixes — and within days the patch was linked to two very different reliability problems: an enterprise deployment failure that produced WSUS/SCCM install errors, and a separate cluster of...

Microsoft's August cumulative update for Windows 11 (KB5063878, OS Build 26100.4946) has been linked in community reports to NVMe SSDs becoming inaccessible after sustained, heavy file writes — an issue that has reopened concerns about storage stability in the 24H2 branch and forced a cautious...
