在Windows 10上安装Hyper-V时，如果收到错误0x800f080c，则表示Windows找不到 Hyper-V 功能。虽然这篇文章着眼于如何解决它，但这里是有关该错误的详细信息：

功能名称Microsoft-Hyper-V未知。无法识别Windows
功能名称。使用/Get-Features选项在图像中查找功能的名称，然后重试该命令。错误：0x800f080c

当您尝试从命令提示符^{(Command Prompt)}或Power Shell安装^{(Power Shell)}Hyper-V时，会发生这种情况。如果 Windows 找不到您要安装的功能，或者命令有问题，您将收到此错误。

修复 Windows 10 上的 0x800f080c Hyper-V 错误

使用以下方法解决错误代码 0x800f080c，该错误代码在使用Hyper-V安装或更改任何内容时发生。

1. 使用正确的命令
2. VirtualBox 问题

您将需要一个管理员帐户来执行下面提到的建议。

1]使用正确的命令

虽然Microsoft Docs有提到需要使用的命令，但它仍然不正确。这是由其中一位用户报告的^{(reported by one of the users)}。所以使用下面提到的命令在Windows 10上启用^{(Windows 10)}Hyper-V是：

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All

Microsoft Docs命令在 -V 和-All之间有一个空格，该空格不应该存在。希望他们尽快改正。

2] VirtualBox问题

如果您在VirtualBox中遇到问题，则需要再次关闭Core Isolation Memory Integrity。

打开Windows Security > Device安全> Core Isolation > Core隔离详细信息 >切换^(Toggle)内存^(Memory)完整性。

如果这不起作用^{(doesn’t work out)}，您可以启用注册表^(Registry)设置。

导航到注册表中的位置，并将Enabled的值设置为0。

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity\Enabled

我希望您能够解决Windows 10上的 0x800f080c Hyper-V 错误。

Fix 0x800f080c Hyper-V error on Windows 10

When installing Hyper-V on Windows 10, if you reсeive an error 0x800f080c, it means that Windows cannot find the Hyper-V feature. While this post looks at how you can resolve it, here is detailed information on the error:

Feature name Microsoft-Hyper-V is unknown.
A Windows feature name was not recognized.
Use the /Get-Features option to find the name of the feature in the image and try the command again.
Error: 0x800f080c

This occurs when you try to install Hyper-V from the Command Prompt or Power Shell. If Windows cannot find the feature you want to install, or the command has an issue, you will receive this error.

Fix 0x800f080c Hyper-V error on Windows 10

Use the following methods to resolve the error code 0x800f080c, which occurs when installing or changing anything with Hyper-V.

1. Use Correct Command
2. VirtualBox issue

You will need an administrator account to execute the below-mentioned suggestions.

1] Use Correct Command

While Microsoft Docs has the command mentioned that needs to be used, it is still incorrect. This was reported by one of the users. So use the command mentioned below to enable Hyper-V on Windows 10 is:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All

The Microsoft Docs command has a space between -V and -All, which should not have been there. Hope they correct it soonest.

2] VirtualBox issue

If you face the problem in VirtualBox, you need to turn Core Isolation Memory Integrity back off again.

Open Windows Security > Device security > Core Isolation > Core isolation details > Toggle on Memory integrity.

If that doesn’t work out, you can enable a Registry setting.

Navigate to the location in the registry, and set the value of Enabled to 0.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity\Enabled

I hope you were able to resolve the 0x800f080c Hyper-V error on Windows 10.
