Oh, I love free stuff, and I love people who make it easier to download free stuff.
Visit the Ninite site, and check off the free applications you want on your computer, such as Firefox, Chrome, iTunes, Audacity, Skype, AVG, Adobe Reader, Gimp… The list is fantastic! (And it reminds me of all the great tools I still need to cover here on Cheapskate Freelancer.)
Once you choose your programs, click to install, and Ninite will manage your installation. This is great when you are doing a full upgrade to Windows 7.
