On which site, numpy, scipy or sourceforge? I tried this:
numpy.org; nothing on that page.
Click 'Getting Numpy' => Obtaining Numpy & SciFi libraries. The only
references to Windows takes me to the sourceforge site (ignoring the
link to do with building).
The sourceforge site (http://sourceforge.net/projects/numpy/files/) has
nothing like that either. It just has 'Looking for the latest version?
Download numpy-1.9.2.zip'. That's the obvious link.
Or I can ignore that and click on the 'NumPy' link. That takes me to a
long list of versions (1.9.2 to 1.0.4).
Nothing that looks like your paragraph 2, or the proper installers.
It's only after examining your link that I realise that each version
number such as 1.9.2 actually opens up a new directory of files. And
*now* I can see that some files are proper installers (which I've
installed and it was a lot smaller and quicker than the Anacondo one).

But I've still found of the above quote.
You see the problem however? Loads of confusing links that all look very
similar, and sometimes just go around in circles?
Why can't they just have that direct link on the numpy home page? Just
for Windows users as presumably everyone else has any problem. And no
one wants to mess around building things from scratch.
