Moving from Windows XP to Windows 7 will be a whole lot easier if you use Ninite. The free online site lets you pick those extra apps you always need to hunt around the web for when you do a clean install.
Once you've checked off your choices among the 59 possibilities, you download an installer (sorry, Windows only) , double-click it and you can just walk away while it loads up all those apps on your fresh operating system. It's even smart enough to avoid installing crapware such as unnecessary toolbars.
We've been testing this routine in its beta phase, and we can tell you it works beautifully. We test a lot of operating systems here, and it's a pain to individually install apps such as Adobe Flash, Adobe Reader (or better yet, Foxit Reader), iTunes, Firefox, Winrar, and many others. Now, with our custom installer, everything is ready to go in minutes.
The company aims to please, asking you to suggest more apps that aren't yet included. It's hard to believe this is free.
