Fix 0x800f080c Hyper-V error on Windows 10


When installing Hyper-V on Windows 10, if you receive 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

0X800F080C Hyper-V error

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.
