Welcome to GARYTOWN 2.0. 

So recently I've run across the most amazing 2 products for when you setup a new computer, or want to update an old computer:
First, you use this: PC Decrapifier to remove all the applications you don't want
Second, you use Ninite to simply install all of the software you want.  You pick what software you want from a list, and download a small installer  When you run the installer, it simply downloads all of the applications you chose and installs them for you, with no interaction!  A little while later, you have it all!
