That does not correspond, on my machine.

I suppose you could read all the subkeys of

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkCards
then match $node{Name} to the first value contained in the "Description" of each subkey entry. Update: Working code that gets the GUID, if it exists: 
use strict;

use Win32::TieRegistry;
use Data::Dumper;

# Get nic info via wmic (not available on all versions of windows)...
my @devs = split(/^\s*\n/m, `wmic nic list brief /format:value`);
my %Regvalues;
shift(@devs);                    # Remove initial blank line



DumpReg();
Dumpwmic( $_ )for (0..15);

sub Dumpwmic{
   my $d = $devs[shift];                # Take the 2nd device
   my %node = split(/[=\n]/, $d);            # Hashify information
   $node{Name} =~s/\s+$//;
   print Dumper(\%node);
   print $Regvalues{ $node{Name} } . "\n";
}

sub DumpReg{

   my $dev="LMachine/SOFTWARE/Microsoft/Windows NT/CurrentVersion/Netw
+orkCards";

   my $key=$Registry->Open($dev, { Access => "KEY_READ", Delimiter => 
+"/" } );
  foreach my $subKey (  $key->SubKeyNames  ) {
     $Regvalues{ $key->{$subKey}->{Description}  } =   $key->{ $subKey
+}->{ServiceName};
     print "$subKey=" . $key->{$subKey}->{Description} . " " .
        $key->{ $subKey}->{ServiceName} . "\n";

  }
}
