遵循本指南：较新的 Windows 10 安装在会话前初始化阶段大约需要 20 分钟
我发现的是：
interval endTime="130463" startTime="0" name="PreSMSS" duration="130463"
然而我找不到任何导致这种滞后的驱动程序。

似乎在引导启动后和系统启动前有 smth 循环/等待，但缺少具体是什么的信息。（我不知道如何对其进行分析或在日志中查找）
（任何建议或教程链接都将非常感谢。谢谢。）

答案1
因此，从摘要中可以看出，PreSMSS 子阶段很慢：
此子阶段会发生什么PreSMSS 子阶段从内核被调用时开始。在此子阶段中，内核初始化数据结构和组件。它还启动PnP 管理器，它初始化在 OSLoader 阶段加载的 BOOT_START 驱动程序。当 PnP 管理器检测到设备时，它会加载并初始化设备的驱动程序
视觉提示 PreSMSS 大约在“正在加载 Windows”启动画面出现时开始。PreSMSS 结束时没有明确的视觉提示。
在您的情况下，它不是一个需要花费太长时间的设备，而是一个未出现在此摘要中的驱动程序。
打开 ETL 后，将CPU 使用率（采样）到分析窗格：
您会看到系统进程在启动开始时占用了较高的 CPU 时间长达 130 秒。
所以你需要分析系统进程的CPU使用率。在您的情况下，它表明klbackupdisk.sys涉及卡巴斯基过滤器驱动程序 ( )：
尝试删除卡巴斯基。接下来我看到 BitLocker 驱动器加密驱动程序 (fvevol.sys)。如果您已加密驱动器，请撤消此操作并查看启动是否更快。
