我的 Windows 11 安装启动缓慢，有时需要几十分钟，有时需要一个小时或更长时间。为了排除常见问题，我已经执行以下操作：
- 全面病毒扫描（未检测到问题）
- 以安全模式启动（速度缓慢持续存在）
- 干净启动（速度缓慢依然存在）
- 高级启动 - 启动修复（未检测到问题）
- 检查 SSD 健康状况（无问题）
- SFC /scannow（未检测到问题）
- DISM /online /cleanup-image /restorehealth（未检测到问题）
- 通过 ISO 进行 Windows 就地修复（速度缓慢依然存在）
- HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System 设置 VerboseStatus=1（与以前的行为没有变化）
在没有其他想法的情况下，我检查了事件查看器中的 Microsoft-Windows-Diagnostics-Performance/Operational 日志。令我惊讶的是，我发现了以下“启动降级”事件（ID：101）。其中唯一不是 Windows 系统进程的是0补丁，这是一项轻量级的零日漏洞修补服务，我已经运行了好几年，没有出现任何问题。另外值得注意的是，虽然“关键”事件“启动性能监控”表明启动大约需要 2 分钟，但实际花费的时间肯定比这更长（大多数时候，计算机处于完全黑屏状态，只有电源指示灯和驱动器 LED 亮起）。
我不知道是什么原因导致这些程序启动速度如此缓慢。我还能做些什么来改善这种情况吗？
