Ninite is a new freeware application that helps install all the 3rd party applications most people want after a clean installation of Windows.  If your getting Windows7 This is a must have, but also works for XP and Vista.

  It is pretty simple to use, but you do need a internet connection.  Simply go to Ninite, check off which applications you want installed, download the custom installation file, and run the Ninite file.  Just sit back and it will do the work for you.  What is nice is that Ninite is intelligent enough to avoid toolbars, crapware, or offers that me be snuck in with any of the programs!  Once finished, Ninite leave no other traces behind except the install file – which you can delete.
