Powershell-如何使用Get-WindowsOptionalFeature命令“打开和关闭Windows功能”

很好你找到了一个适合你的答案,但是。。。

但是,不需要函数来使用通配符。就这样。。。

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

我想出来了。

$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
    }
}

上面的代码返回:

There are 170 Windows features available


FeatureName : IIS-WMICompatibility
State       : Disabled

因此,要启用该功能,可以运行:

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

注意:你必须跑 Enable-WindowsOptionalFeature

您可以通过运行以下命令验证它是否已启用:

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