I have been working lately on the iisnode project to provide good support for running node.js applications on Windows. Since both node.js itself as well as iisnode version very frequently at this stage, I have set up a set of stable URL aliases that will always point to the latest installation packages. If you plan to create any web content related to running node.js on Windows (blogs, tweets) and you need to link to the installation packages, it is a good idea to use the links below unless you must attach to a particular version.
Here are the links:
node.js (x86): http://go.microsoft.com/?linkid=9784334
iisnode for iis7 express (x86): http://go.microsoft.com/?linkid=9784329
iisnode for iis7 (x86): http://go.microsoft.com/?linkid=9784330
iisnode for iis7 (x64): http://go.microsoft.com/?linkid=9784331
