很奇怪。我在我的 Win10 1803 Lenovo T450 (8GB RAM) 笔记本电脑上启用了 Hyper-V 功能。尝试创建第一个 Windows Server VM，但出现错误：
“...虚拟机管理程序未运行”
谷歌搜索并找到了这个有用的页面，运行bcdedit /set hypervisorlaunchtype auto重新启动并且一切正常，虚拟机已加载并运行。
下次重新启动笔记本电脑时，它卡在登录阶段，屏幕变黑，但有光标，我仍然可以通过 ctrl+alt+del 访问任务管理器。注意到 explorer.exe 不在进程列表中，但尝试从“运行新任务”启动它没有任何效果。最后我意识到，如果我在关闭 wifi 的情况下重新启动，它将一直登录到桌面，但发生了一些奇怪的事情
- Chrome 根本无法打开。chrome.exe 很快就会从进程列表中出现又消失。
- 无法打开提升的 Powershell 管理窗口，只能打开然后关闭。非提升的 Powershell 可以成功打开
- 无法打开许多控制面板小程序，包括 Hyper-V 管理器
如果我恢复hypervisorlaunchtype到关闭状态并重新启动，则一切都正常，打开 wifi 即可正常登录，上述三项已修复，但我的虚拟机不会再次启动“...虚拟机管理程序未运行”，显然是因为我已经关闭了虚拟机管理程序。
我尝试过的事情：
- 在 UEFI 中禁用并重新启用虚拟化
- 关闭并打开 Hyper-V 功能
- 事件查看器中没有明显异常
- 在 UEFI 中运行内存诊断快速测试 - 通过
