The August 2025 Patch Tuesday cumulative for Windows 11 (KB5063878) has introduced an unexpected and painful wrinkle for live broadcasters: NDI-based streaming through OBS and other production tools can stutter, lag, and drop frames — even on healthy networks — and Microsoft has acknowledged the...

Microsoft and several SSD vendors are investigating reports that the August 12, 2025 cumulative update for Windows 11 24H2 (KB5063878, OS Build 26100.4946) can trigger a reproducible storage regression where some SSDs vanish from the operating system during sustained, large sequential writes — a...
A wave of reproducible reports and a parallel burst of misinformation have combined to create one of the more consequential Patch Tuesday headaches in recent memory: Microsoft’s August 12, 2025 cumulative for Windows 11 (KB5063878) has been linked to SSDs disappearing under sustained, heavy...
Phison has confirmed it is investigating a widespread storage regression tied to Windows 11’s August cumulative update (KB5063878) while simultaneously denouncing and legally challenging a circulated document that falsely claims to be an internal Phison report linking the problem exclusively to...
Microsoft has temporarily paused the roll‑out of recent Windows updates after a cascade of high‑impact problems—including broken recovery tools, WSUS installation failures, and reports of storage devices becoming inaccessible—hit a subset of users and enterprise environments nationwide...

Microsoft’s August cumulative for Windows 11 (KB5063878, OS Build 26100.4946) has been linked by multiple community tests and specialist outlets to a narrow but severe storage regression in which some NVMe SSDs can suddenly become unresponsive or disappear during sustained, large writes — a...
Microsoft's August Patch Tuesday set off a chain reaction: the security update that fixed scores of vulnerabilities also broke Windows' own recovery tools for many users, and Microsoft was forced to ship out-of-band (OOB) emergency patches to undo the damage. The recovery failure — which could...
