  SELECT ServerName = @@servername,

  InstanceName = CASE WHEN CharIndex('\', @@ServerName) = 0 THEN NULL

  ELSE SubString(@@ServerName, CharIndex('\', @@ServerName)+1, 100) END;

  if by reg you mean Registery

  Exec xp_regenumvalues N'HKEY_LOCAL_MACHINE',

  N'SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names\SQL';

  I am fundamentally opposed to going to the registry unless it is ABSOLUTELY necessary.. And in this case it isn't..

  SELECT InstanceName = SERVERPROPERTY('InstanceName')

  It will return NULL for a default instance..
