it's hardly productivity! if somebody uses those cracks, they then get to... (dadadadah dah dah daaaah!!!) USE WINDOWS XP!!!
talk about a booby prize!
remember there's at least one alternative operating system out there with several advantages over XP (depending on your requirements) that are free anyway! The main reason you can crack windows, but not linux, is that linux does not need to be activated! what a brainwave eh?!?!?
