How do you check to see if Hyper-V is enabled using PowerShell?
提问by Evan Amara
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.
我正在尝试编写一个 PowerShell 脚本来检查 Windows 可选功能以查看是否安装了 Hyper-V。但是，我的代码不起作用。即使禁用了 Hyper-V，脚本也会输出它已启用。
#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.
代码运行时没有错误。

I believe it has to do with your ifcondition, try this:
我相信这与你的if情况有关，试试这个：
if($hyperv.State -eq "Enabled")
The =sign is not going to work, you need to do it PowerShell way
该=标志不起作用，您需要以 PowerShell 的方式进行

Here's the full powershell script that works for me. Just copy and paste it into an elevated powershell then press enter.
这是适用于我的完整 powershell 脚本。只需将其复制并粘贴到提升的 powershell 中，然后按 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.
一种更简单的方法是通过单击“开始”按钮并键入 Services.msc 并向下滚动到 Hyper-V 主机计算服务并查看它是否正在运行来转到服务。还要检查 Hyper-V 虚拟机管理服务。
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.
如果它们都在运行，您可以放心地假设 Hyper-V 正在运行并且处于活动状态。我的机器 Windows 10 Pro 和 VMWARE Workstation 14。
