How do you check to see if Hyper-V is enabled using PowerShell?

问题

I am trying to write a PowerShell script that checks the Windows Optional Features to see if Hyper-V is installed. However, my code is not working. Even when Hyper-V is disabled, the script outputs that it is already enabled.

#Requires -RunAsAdministrator

# Get the Hyper-V feature and store it in $hyperv
$hyperv = Get-WindowsOptionalFeature -FeatureName Microsoft-Hyper-V-All -Online

# Check if Hyper-V is already enabled.
if($hyperv.State = "Enabled") {
    Write-Host "Hyper-V is already enabled."
} else {
    Write-Host "Hyper-V is disabled."
}

There is no error when the code is run.

I believe it has to do with your if condition, try this:

if($hyperv.State -eq "Enabled")

The = sign is not going to work, you need to do it PowerShell way

Here's the full powershell script that works for me. Just copy and paste it into an elevated powershell then press enter.

$hyperv = Get-WindowsOptionalFeature -FeatureName Microsoft-Hyper-V-All -Online
# Check if Hyper-V is enabled
if($hyperv.State -eq "Enabled") {
    Write-Host "Hyper-V is enabled."
} else {
    Write-Host "Hyper-V is disabled."
}

An easier way to do that is to go to Services by clicking the Start button and typing Services.msc and scrolling down to the Hyper-V Host Compute Service and seeing if it running. Also check the Hyper-V Virtual Machine Management service.

If they are both running you can safely assume that Hyper-V is running and active. My machine Windows 10 Pro with VMWARE Workstation 14.
