Answer 1

嗯，你找到了一個適合你的答案，但......

但是，您不需要使用通配符的函數。 這樣做......

Get-WmiObject -Class $Win32_OperatingSystem

# List features all
(Get-WindowsOptionalFeature -Online -FeatureName '*') | Format-Table -Autosize
(Get-WindowsOptionalFeature -Online -FeatureName '*').Count
144

# List features for IIS
(Get-WindowsOptionalFeature -Online -FeatureName '*IIS*').Count
54

# List features for wmi
(Get-WindowsOptionalFeature -Online -FeatureName '*wmi*').Count
2

# List features for IIS or wmi
(Get-WindowsOptionalFeature -Online -FeatureName '*iis*|*wmi*').Count
55


# List features for IIS or wmi or hyperv
(Get-WindowsOptionalFeature -Online -FeatureName '*iis*|*wmi*|*hyper*').Count
63

Answer 2

我想到了。

以下代碼用於通過使用通配符查找功能

$features = Get-WindowsOptionalFeature -Online
Write-Host ('There are ' + $features.Count + ' Windows features available') -ForegroundColor Green
foreach($feature in $features)
{
    if($feature.FeatureName -like "*IIS*WMI*") # wildcard search
    {
        $feature
    }
}

上面的代碼返回：

There are 170 Windows features available


FeatureName : IIS-WMICompatibility
State       : Disabled

因此，要啟用該功能，您可以運行：

$feature = Get-WindowsOptionalFeature -Online -FeatureName 'IIS-WMICompatibility'
Enable-WindowsOptionalFeature $feature -Online

注意：您必須以管理員身份運行Enable-WindowsOptionalFeature ...

您可以通過運行以下命令驗證它是否已啟用：

(Get-WindowsOptionalFeature -Online -FeatureName 'IIS-WMICompatibility').State
