Win32_OperatingSystem: Querying Operating System Info Remotely (CIM Session)

<#
.SYNOPSIS
    WQL reference: querying Operating System Info on a remote computer (Win32_OperatingSystem).

.DESCRIPTION
    The same WQL SELECT statement used locally works unchanged against a
    remote computer — only the connection changes. This uses a CIM
    session (WinRM-based), the modern replacement for the old DCOM-based
    -ComputerName parameter on Get-WmiObject.

.PARAMETER ComputerName
    Name or IP address of the remote computer. WinRM must be enabled
    there (Enable-PSRemoting) and you need admin rights on it.

.EXAMPLE
    .\OperatingSystemRemote.ps1 -ComputerName SERVER01
