禁掉 Hyper-V

管理员模式运行 CMD:

//To disable:bcdedit /set hypervisorlaunchtype off//To enable:bcdedit /set hypervisorlaunchtype auto

问题症状

讲道理用上面的方法是可以禁掉 Hyper-V 的，但我尝试了无数次都不可以。包括在 Android Studio 中启动模拟器时提示让我 disable Hyper-V 的方法。

但每次重启之后还是启动不了 Android Studio 中的 x86 模拟器。

问题原因

这是微软 Group Ploicy 的原因

Windows 搜索框中输入 System information:, 右下角：

好吧，直接看解决方案吧

管理员模式打开 CMD, 运行下面的命令：

mountvol X: /scopy %WINDIR%\System32\SecConfig.efi X:\EFI\Microsoft\Boot\SecConfig.efi /Ybcdedit /create {
  0cb3b571-2f2e-4343-a879-d86a476d7215} /d "DebugTool" /application osloaderbcdedit /set {
  0cb3b571-2f2e-4343-a879-d86a476d7215} path "\EFI\Microsoft\Boot\SecConfig.efi"bcdedit /set {bootmgr} bootsequence {
  0cb3b571-2f2e-4343-a879-d86a476d7215}bcdedit /set {
  0cb3b571-2f2e-4343-a879-d86a476d7215} loadoptions DISABLE-LSA-ISO,DISABLE-VBSbcdedit /set {
  0cb3b571-2f2e-4343-a879-d86a476d7215} device partition=X:mountvol X: /d

之后再管理员模式运行 CMD:

//To disable:bcdedit /set hypervisorlaunchtype off

解释性的： Resolution

1. Disable the group policy setting that was used to enable Credential Guard.

   a. On the host operating system, click Start > Run, type gpedit.msc, and click Ok. The Local group Policy Editor opens.

   b. Go to Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard > Turn on Virtualization Based Security.
   Select Disabled.
   c.Select Disabled.

2. Go to Control Panel > Uninstall a Program > Turn Windows features on or off to turn off Hyper-V.

   Select Do not restart.

3. Delete the related EFI variables by launching a command prompt on the host machine using an Administrator account and run these commands:

mountvol X: /scopy %WINDIR%\System32\SecConfig.efi X:\EFI\Microsoft\Boot\SecConfig.efi /Ybcdedit /create {
  0cb3b571-2f2e-4343-a879-d86a476d7215} /d "DebugTool" /application osloaderbcdedit /set {
  0cb3b571-2f2e-4343-a879-d86a476d7215} path "\EFI\Microsoft\Boot\SecConfig.efi"bcdedit /set {bootmgr} bootsequence {
  0cb3b571-2f2e-4343-a879-d86a476d7215}bcdedit /set {
  0cb3b571-2f2e-4343-a879-d86a476d7215} loadoptions DISABLE-LSA-ISO,DISABLE-VBSbcdedit /set {
  0cb3b571-2f2e-4343-a879-d86a476d7215} device partition=X:mountvol X: /d

**Note**: Ensure X is an unused drive, else change to another drive.

上面的 Resolution 居然还有中文的。。。
