Abfrage erstellen für mehrere PCs
>>> CSV-fILE erstellen mit:

Server,WMIObject
lon-cl1,win32_service
nyc-dc1,win32_bios

Abfrage mit csv
>>> Powershell befehl = Import-csv .\liste.csv

$liste = Import-csv .\liste.csv
$liste | foreach-object {get-wmiobject $_.wmiobject -computername $_.server}

Create_LocalUser.ps1
## Zum erstellen von Usern
## aus einem csv file

Import-Csv users.csv | ForEach-Object {
$target = [ADSI]"WinNT://."
$newuser = $target.Create("user", $_.Name)
$newuser.SetPassword("Password1")
$newuser.SetInfo()
$newuser.psbase.InvokeSet('AccountDisabled', $false)
$newuser.SetInfo()
}

The CSV file is structured

Name
User1
User2
User3
User4
User5
