现在输出：
预期输出......每个用户可能低于另一个用户，而其他事情相同......

Answer 1

现在，您不断覆盖 Process 块内的 $PCInfo 值，然后在最后输出最后分配的值。

完全删除对$PCInfo的赋值，并在创建后立即输出对象。您可能还想显式传递 $computer 作为 Get-CimInstance 的远程计算机名称进行查询：

要将帐户写入文件，只需通过管道传输函数的输出即可到 Export-Csv 或类似的：

Get-PCinfo -ComputerName pc01,pc02,pc03 |Export-Csv path\to\output.csv -NoTypeInformation
