removing words from a line output powershell - powershell

Question

I have a powershell command with below output, The command output shows the active NIC adapter and NIC adapter name differ in each machine. But what I am looking here is, in one server active NIC adapter is Local Area Connection and in another one it is Ethernet.This will differ in all VM's
PS C:\> netsh interface ipv4 show interface |where { $_ -match '\sconnected' -and $_ -notmatch 'loopback'}
12 5 1500 connected **Local Area Connection**
PS C:\>
PS C:\> netsh interface ipv4 show interface |where { $_ -match '\sconnected' -and $_ -notmatch 'loopback'}
12 5 1500 connected **Ethernet**
PS C:\>
I want only the adapter name to be captured (eg: Local Area Connection\Ethernet etc).
Can anyone help me modifying the command so that I will get the NIC adapter name without any white space as output?
The output should be like below
Local Area Connection
Ethernet
Ethernet 2

If you are running this on a Windows 8 or Server 2012 or newer operating system you can use the Get-NetAdapter cmdlet instead to get the result you want:
Get-NetAdapter | Where {$_.Status -eq 'Up'} | Select -ExpandProperty Name
On an older OS you could try this, which splits the text for each interface by the word "connected" and it's trailing whitespace using the regex special character \s and then return the second item of that split:
$Interfaces = netsh interface ipv4 show interface | where { $_ -match '\sconnected' -and $_ -notmatch 'loopback'}
$Interfaces | ForEach-Object {
($_ -Split 'connected\s+')[1]
}
Or here is another option that avoids using the -split operator and instead uses a regex lookbehind to match 'connected' followed by 5 spaces in the string before what we want to return:
$Interfaces = netsh interface ipv4 show interface | where { $_ -notmatch 'loopback'}
$Interfaces | ForEach-Object {
[regex]::matches($_, '(?<=connected\s{5})(.*)').value
}
