How to install Hyper - V if i can´t - The feature name Microsoft-Hyper-V is unknown.

Question

Hello, I have a problem that when I go to activate Windows features or go to cmd to enter the Hyper V activation command, it tells me that the name of the Microsoft Hyper V feature is unknown. Can anyone help me? Specifically says me this:

Error: 0x800f080c

The feature name Microsoft-Hyper-V is unknown.

The name of a Windows feature was not recognized.

Use the /Get-Features option to find the feature name in

the image and try the command again.

Hi,

The Microsoft-Hyper-V feature could have been removed. You can restore the removed feature from the Windows image with DISM. Say the image is mounted to the Z drive, run

Dism /Online /Enable-Feature /FeatureName:Microsoft-Hyper-V /Source:Z:\sources\SxS /LimitAccess

Please refer to this link for the detailed steps.
