Die Informationen lassen sich auch direkt aus der Registry abfragen ohne Funktion:

(Get-ItemProperty -Path “HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion” -Name EditionID).EditionID
(Get-ItemProperty -Path “HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion” -Name ReleaseId).ReleaseId
(Get-ItemProperty -Path “HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion” -Name CurrentBuild).CurrentBuild
(Get-ItemProperty -Path “HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion” -Name ProductId).ProductId

Installationsdatum ermitteln:

$InstallDate = (Get-ItemProperty -Path “HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion” -Name InstallDate).InstallDate
$1970 = Get-Date -Day 1 -Month 1 -Year 1970
$InstallDate = [System.TimeZone]::CurrentTimeZone.ToLocalTime($1970).AddSeconds($Seconds)
Write-Host InstallDate: $InstallDate

Oder über eine CIM-Klasse

(Get-CimInstance -ClassName Win32_OperatingSystem -Namespace root/cimv2).BuildNumber
