How to disable Hyper-V on Windows 11/10

Open the System Information panel.

This indicates that Hyper-V monitoring has been detected, and at this time, VT-x will be hidden by Hyper-V.

Run PowerShell commands to check the status of Windows Hyper-V features.

$features = @(
    "Microsoft-Hyper-V",
    "Microsoft-Hyper-V-All",
    "HypervisorPlatform",
    "VirtualMachinePlatform",
    "Containers-DisposableClientVM"  # Windows Sandbox
)
foreach ($feature in $features) {
    $state = Get-WindowsOptionalFeature -Online -FeatureName $feature | Select-Object State
    Write-Host "$feature : $($state.State)"
}

===>
Microsoft-Hyper-V : Enabled
Microsoft-Hyper-V-All : Enabled
HypervisorPlatform : Enabled
VirtualMachinePlatform : Enabled
Containers-DisposableClientVM : Disabled

Turn off these Hyper-V features.

Restart the computer.

Running the PowerShell command again shows that the Hyper-V features are now disabled.

===>

Microsoft–Hyper–V : Disabled

Microsoft–Hyper–V–All : Disabled

HypervisorPlatform : Disabled

VirtualMachinePlatform : Disabled

Containers–DisposableClientVM : Disabled

Write-Host "VT-x: $((Get-WmiObject Win32_Processor).VirtualizationFirmwareEnabled)" -ForegroundColor Cyan; 
Write-Host "Hyper-V: $((Get-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V).State)" -ForegroundColor Cyan
Write-Host "HypervisorPresent: $((Get-CimInstance Win32_ComputerSystem).HypervisorPresent)" -ForegroundColor Cyan

The PowerShell command output still indicates that ‘HypervisorPresent’ is True.

PS C:\Windows\system32> Write-Host “VT-x: $((Get-WmiObject Win32_Processor).VirtualizationFirmwareEnabled)” -ForegroundColor Cyan;
VT-x: False
PS C:\Windows\system32> Write-Host “Hyper-V: $((Get-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V).State)” -ForegroundColor Cyan
Hyper-V: Disabled
PS C:\Windows\system32> Write-Host “HypervisorPresent: $((Get-CimInstance Win32_ComputerSystem).HypervisorPresent)” -ForegroundColor Cyan
HypervisorPresent: True
PS C:\Windows\system32>

Run PowerShell commands to check Device Guard status.

Get-ComputerInfo -Property "DeviceGuard*"

====>

DeviceGuardSmartStatus : Off

DeviceGuardRequiredSecurityProperties : {0}

DeviceGuardAvailableSecurityProperties : {BaseVirtualizationSupport, DMAProtection, 5, 6…}

DeviceGuardSecurityServicesConfigured : {HypervisorEnforcedCodeIntegrity}

DeviceGuardSecurityServicesRunning : {HypervisorEnforcedCodeIntegrity}

DeviceGuardCodeIntegrityPolicyEnforcementStatus : EnforcementMode

DeviceGuardUserModeCodeIntegrityPolicyEnforcementStatus : Off

Open the Local Group Policy Editor, navigate to Virtualization-Based Security, and set it to Disabled.

Restart the computer.

The latest PowerShell output indicates that VT-x is true, and hypervisorpresent is false.

PS C:\Windows\system32> Write-Host “VT-x: $((Get-WmiObject Win32_Processor).VirtualizationFirmwareEnabled)” -ForegroundColor Cyan;
VT-x: True
PS C:\Windows\system32> Write-Host “Hyper-V: $((Get-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V).State)” -ForegroundColor Cyan
Hyper-V: Disabled
PS C:\Windows\system32> Write-Host “HypervisorPresent: $((Get-CimInstance Win32_ComputerSystem).HypervisorPresent)” -ForegroundColor Cyan
HypervisorPresent: False
PS C:\Windows\system32>

The VirtualBox “Enable Nested VT-x/AMD-V” option is enabled.

Open Windows Security, navigate to Device Security, click on Core Isolation, and set Memory Integrity to ON.
Note that at this point, hypervisorpresent will also be True.
