    目前还在 1703,不过 1809 才有 dxr 所以只能上了

    linux 下可以关闭 l1tf/meltdown/spectre 保护, microcode 可以只更新到 2017 年的
    避免 io 效能倒退 10 年

    win10pro 似乎没有办法关闭? 找到的 kb 只适用 win10server
    装 1809 後有办法让 microcode 只更新到 2017 年版本吗?

    还是只能装新机 amdyes 就没有这些问题了

    有办法的，注册表设置一下就行。

    配置一样对其他桌面版本的 Windows 有效。

    比较老的应用，不过原理估计跟改注册表一样
    不是很明白楼主为什么要关掉这个防护，不是说 4 代及之后的 u 影响较小吗，不至于缺那点 io 性能吧？
