Ninite is a web app that lets you quickly download groups of software. Useful for quickly setting up computers, this automatically downloads programs in the right language without any toolbars or additional files.
The Ninite interface is just one page, with categorized popular applications. To install a package you simply select those programs you need, click 'get installer' and then the download starts. The selection of applications is good, from browsers and messengers, to security and file sharing software. It's not comprehensive, but has what most people will need to get started on a fresh PC.
If you think there's an important application missing, you can submit it for consideration. Ninite always gives you the most up to date version of a program, so it's no use if you for some reason need an old one.
If you want to quickly download essential apps, Ninite is a neat way to do it without much effort.
