Try that firewall, its a bit old now, but its probably the best I've ever used. It's free, and just as a warning it will pop up a free registration form every time it starts, any you have to click 'register later'. You can't register it because the webpage it sends the registration data to no longer exists (Sygate were bought out by Symantec, who dissolved Sygate and discontinued their products, attempting to flog Norton crap instead. Sygate free edition is still far superior to anything Norton/Symantec produce)

unfortunately, as far as I'm aware, it doesn't work on Vista.

 

that isn't likely to work as programs have registry entries which cannot easily be copied.

 

cracked has nothing to do with it. The registry stores important information about programs, including configuration settings, where on the screen to draw the window etc.
