Ninite is like Automatix for Windows

Ninite lets you construct a custom installation package containing different software of your choice. This package then installs all of the applications in one go, using their default settings — it also tries to skip any toolbar installations and other annoyances automatically.

Automatix was a dangerous abomination, code-wise, but its concept was noble. Ninite seems to be striving for something similar (albeit saner) on Windows. If you’re lazy, and you don’t mind trusting a third party too much, you should give it a try.
