Answer 1

快速解决方法:可以使用临时clixml文件存储Get-WindowsOptionalFeature cmdlet的结果：

$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
    }
}
