Win32_Environment: Querying Environment Variables Remotely (CIM Session)

<#
.SYNOPSIS
    WQL reference: querying Environment Variables on a remote computer (Win32_Environment).

.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
    .\EnvironmentRemote.ps1 -ComputerName SERVER01

$wqlQuery = "SELECT Name, VariableValue, UserName FROM Win32_Environment"
$session = New-CimSession -ComputerName $ComputerName

try {
    Get-CimInstance -CimSession $session -Query $wqlQuery | Format-Table -Property Name, VariableValue, UserName -AutoSize
} finally {
    Remove-CimSession -CimSession $session
}
