About this tag
The meltdown spectre tag covers discussions about the Meltdown and Spectre CPU vulnerabilities and their impact on Windows systems. Content includes the January 2018 Windows updates that caused boot failures on AMD-based PCs, leading Microsoft to pause distribution. Another thread details how a Windows 7 Meltdown patch from early 2018 inadvertently exposed kernel memory to unprivileged code, a regression fixed in March. These threads highlight real-world issues with speculative-execution vulnerability mitigations, including compatibility problems and security regressions on Windows 7, Windows Server 2008 R2, and AMD hardware.

    Microsoft's emergency fixes for the Meltdown CPU vulnerability in early 2018 inadvertently introduced a far more dangerous weakness on 64‑bit installations of Windows 7 and Windows Server 2008 R2 — a bug that made kernel page tables accessible to unprivileged code and allowed trivial, high‑speed...
