One of the most commonly reported issues with Hyper-V on Windows 11 is the appearance of the error message “The VM session was aborted. Result code: E_FAIL (0x80004005).” This error can occur for various reasons, but often it’s related to compatibility or configuration problems.

To troubleshoot this error, try the following steps:

1. Update Hyper-V Integration Services: Ensure that your virtual machines are running the latest version of the Hyper-V Integration Services. You can do this by opening the Hyper-V Manager, selecting the problematic VM, and clicking “Integrate Services” in the actions pane. If updates are available, install them and try starting the VM again.

2. Upgrade the VM Configuration Version: The Update-VMVersion PowerShell cmdlet can be used to upgrade the configuration version of your VMs. This is particularly important if you’re migrating VMs from older versions of Windows to Windows 11. Run the following commands in an elevated PowerShell window:

powershell
Get-VM | Select-Object -ExpandProperty Version
Update-VMVersion -Name <VMName> -Force

Replace <VMName> with the name of your virtual machine. This will update the VM configuration to the latest version, which may resolve the error.

1. Check Virtual Switch Configurations: In some cases, issues with virtual switches can cause the “E_FAIL (0x80004005)” error. According to reports, the Windows 11 22H2 update may have introduced problems with virtual switch configurations. To address this, follow these steps:

“`powershell
# List the current virtual switches
Get-VMSwitch

# Untagging the filter settings
Get-VMSwitch | ForEach-Object { Set-VMSwitch -Name $_.Name -AllowManagementOS $true }

# Restart the affected VMs
Restart-VM -Name
“`

This will remove any problematic filter settings and restore the virtual switch functionality, allowing your VMs to start correctly.

By addressing these common issues, you should be able to get your Hyper-V environment up and running on Windows 11. Remember, as with any IT solution, it’s essential to stay informed about the latest updates, known issues, and best practices to ensure a smooth and reliable virtual machine experience.
