Can anyone tell me or lead me to a site that lists all the dell models with a FACTORY SLIC 2.1? update for Win 7... Especially Optiplex or Latitude? (any Dell model is fine) I own a computer shop and this is very important to me and my customers so I can upgrade "legally". I know that the Optiplex 360 A02 has it, anyone know of any others? Thank you in advance.
