Answer 1

快速&髒解決辦法：你可以用臨時CLIXML文件來存儲獲取-WindowsOptionalFeature cmdlet的結果：

$tempFile = [System.IO.Path]::GetTempFileName() 
try 
{ 
    Start-Process powershell -Wait -Verb runAs -ArgumentList "-Command Get-WindowsOptionalFeature -Online | Export-Clixml -Path $tempFile" 

    $features = Import-Clixml -Path $tempFile 

    # Use $features 
} 
finally 
{ 
    if (Test-Path $tempFile) 
    { 
     Remove-Item -Path $tempFile -Force -ErrorAction Ignore 
    } 
}
