How to Fix the “Feature Name Microsoft-Hyper-V Is Unknown” 0x800f080c Error
Your Windows 10 and 11 running systems come with an optional virtualization tool, Hyper-V. If you want, it’s possible to enable it using a DISM command in PowerShell and Command Prompt.
However, the command to enable Hyper-V sometimes can return the “A Windows features name was not recognized” or the “Feature Name Microsoft-Hyper-V is Unknown” error 0x800f080c.
Often this error is triggered due to issues with the DISM command. If you try to enable Hyper-V in Windows 11 Home and encounter the error, it could be due to issues with the script. In any case, here are a few troubleshooting steps to fix this error and enable Hyper-V in Windows.
1. Check the Command for Typos
The most common contributor to this error is the use of an incorrect command. You can use the following command in PowerShell to enable Hyper-V in Windows 11 Pro, Edu, and Enterprise edition of the operating system:
If you think you have used the correct command, look for unnecessary spaces between Microsoft-Hyper-V-All. Rerun the command and check if the error is resolved.
If the issue persists, check out the other ways toenable Hyper-V in Windows 11.
2. Check Your Hyper-V Batch Script for Errors
Hyper-V is only available on the Pro, Edu, and Enterprise edition of the Windows operating system. If you are using Home, you’ll need to use a batch script workaround toenable Hyper-V in Windows 11 Home.
If you encounter the 0x800f080c error with the Hyper-V script, check it for errors. The batch script to enable Hyper-V should look something like this:
After verifying the script, run the script as administrator and check if the error is resolved.
3. Turn Off the Core Isolation Memory Integrity Feature
If the error is triggered on a virtual machine, such as VirtualBox, check to see if the memory integrity feature is causing the error.
Memory integrity is part of Windows 11’s Core Isolation, a virtualization-based security feature. When enabled, it prevents threat actors from inserting malicious code into high-security system processes.
Follow these steps to disable the memory integrity feature in Windows 11:

Not Linux, not Windows. Something better.
My foolproof plan is to use Windows 10 until 2030, with the latest security updates.
