I'd like to make this powershell work in Windows 7 (with an appropriate substitution for Get-NetConnectionProfile)

Question

I have this script that works in Windows 10+ but I need it to also work in Windows 7.

$Adapters=Get-NetAdapter -ErrorAction SilentlyContinue | ?{$_.Status -eq "Up"} 
$IPAddresses=@()
$Profiles=@()
foreach ($Adapter in $Adapters)
{
    $IPaddresses+=Get-NetIPAddress -InterfaceIndex $($Adapter.InterfaceIndex) -AddressFamily IPv4 -ErrorAction SilentlyContinue
    $Profiles+=Get-NetConnectionProfile -InterfaceIndex $($Adapter.InterfaceIndex) -ErrorAction SilentlyContinue
}
$Domain = $IPAddresses | ? {$_.InterfaceIndex -eq ($Profiles | ? {$_.NetworkCategory -eq "DomainAuthenticated"}|select InterfaceIndex -ExpandProperty InterfaceIndex)}
$Public = $IPAddresses | ? {$_.InterfaceIndex -eq ($Profiles | ? {$_.NetworkCategory -eq "Public"}|select InterfaceIndex -ExpandProperty InterfaceIndex)}
if (($Domain -ne $null) -and ($Public -ne $null))
{
    Write-Host "Public Interface found on $($env:COMPUTERNAME)"
}
else {Write-Host "None"}

The goal is to test if I have a DomainAuthenticated Network connection and then to return the hostname of the machine IF there is ALSO an active PUBLIC network connection. The problem is that Get-NetworkConnectionProfile is only available in OSs ABOVE W7.

What is the pre-W10 equivalent to this?

OK - this appears to be the solution that I was looking for. If anyone sees anything glaringly wrong, just shout out!

$OSVer = (Get-CimInstance Win32_OperatingSystem).version

if ($OSVer -like "10*") {

    $Adapters = Get-NetAdapter -ErrorAction SilentlyContinue | ? { $_.Status -eq "Up" } 
    $IPAddresses = @()
    $Profiles = @()
    foreach ($Adapter in $Adapters) {
        $IPaddresses += Get-NetIPAddress -InterfaceIndex $($Adapter.InterfaceIndex) -AddressFamily IPv4 -ErrorAction SilentlyContinue
        $Profiles += Get-NetConnectionProfile -InterfaceIndex $($Adapter.InterfaceIndex) -ErrorAction SilentlyContinue
    }
    $Domain = $IPAddresses | ? { $_.InterfaceIndex -eq ($Profiles | ? { $_.NetworkCategory -eq "DomainAuthenticated" } | select InterfaceIndex -ExpandProperty InterfaceIndex) }
    $Public = $IPAddresses | ? { $_.InterfaceIndex -eq ($Profiles | ? { $_.NetworkCategory -eq "Public" } | select InterfaceIndex -ExpandProperty InterfaceIndex) }
    if (($Domain -ne $null) -and ($Public -ne $null)) {
        Write-Host "Public Interace on $($env:COMPUTERNAME)"
    }
    else { Write-Host "None" }
}
else {

    $Adapters = Get-WmiObject -Class Win32_NetworkAdapter -Filter "NetEnabled='True'"
    $IPAddresses = @()
    $Profiles = @()
    foreach ($Adapter in $Adapters) {
        $IPAddresses += Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter "Index='$($Adapter.Index)'" | Where-Object { $.IPAddress -ne $null -and $.IPSubnet -ne $null -and $.DefaultIPGateway -ne $null }
        $Profiles += Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter "Index='$($Adapter.Index)'" | Select-Object -ExpandProperty Description
    }
    $Domain = $IPAddresses | ? { $.IPConnectionMetric -lt 50 -and $.DefaultIPGateway -ne $null -and $Profiles[$_.Index - 1] -match "domain" }
    $Public = $IPAddresses | ? { $.IPConnectionMetric -lt 50 -and $.DefaultIPGateway -ne $null -and $Profiles[$_.Index - 1] -match "public" }
    if (($Domain -ne $null) -and ($Public -ne $null)) {
        Write-Host "Public Interace on $($env:COMPUTERNAME)"
    }
    else {
        Write-Host "None"
    }
}
