I wrote a simple tool that emulates the *nix "ifconfig -a" in Delphi and posted it here on SO. However, I would also like to be able to retrieve the adapter's GUID as well. Is there a way to do this in Delphi, without using WMI?
check this windows registry key
HKEY_LOCAL_MACHINE -> SOFTWARE -> Microsoft -> WindowsNT -> CurrentVersion- > NetworkCards
undear each number see the value of the ServiceName
this is the GUID
