What Smart Installer Pack actually does is incorporate a handful of software usually installed on new computers, reinstalled operating systems, etc.

So, SIP was made just to eliminate all the searching around for nothing, waiting, downloading (which can take up a lot of time) and only then installing.

Now, all you have to do is download this Smart Installer Pack and click on the preferred icons - you can choose which software to install.

I'm not a big fan of "software packs" - I prefer to install every program manually and make sure it's well set-up. But this may come useful if you're reinstalling Windows, for example.
