好的，我有一个概念验证脚本，看起来像这样连接到iTunes：
$username = Read-Host "Please enter your userid for the local machine"
$password = Read-Host "Please enter a password to be encrypted" -AsSecureString
$cred = New-Object System.Management.Automation.PSCredential -ArgumentList @($username,$password)
Invoke-Command -ScriptBlock {
$iTunes = New-Object -ComObject iTunes.application
$itunes | gm
} -ComputerName localhost -Credential $cred
但是它返回以下错误：
Retrieving the COM class factory for component with CLSID {DC0C2640-1415-4644-875C-6F4D769839BA} failed due to the following error: 80080005.
+ CategoryInfo : ResourceUnavailable: (:) [New-Object], COMException
+ FullyQualifiedErrorId : NoCOMClassIdentified,Microsoft.PowerShell.Commands.NewObjectCommand
如果它变得有趣，如果我从脚本块中删除-ComputerName localhost -Credential $cred，它可以正常工作：

有谁知道为什么脚本块上的凭据可能导致此问题？
原因是我正在研究一种运行某些iTunes任务的方法，当从LOCAL SYSTEM服务调用时，所以在某种程度上，我正在尝试将呼叫提升回登录用户。
