From the [node.js blog](http://blog.nodejs.org/2011/06/23/porting-node-to-windows-with-microsoft%E2%80%99s-help/):> I'm pleased to announce that Microsoft is partnering with Joyent in formally contributing resources towards porting Node to Windows. As you may have heard in a talk we gave earlier this year, we have started the undertaking of a native port to Windows - targeting the high-performance IOCP API.
> This requires a rather large modification of the core structure, and we're very happy to have official guidance and engineering resources from Microsoft. Rackspace is also contributing Bert Belder's time to this undertaking.
> The result will be an official binary node.exe releases on nodejs.org, which will work on Windows Azure and other Windows versions as far back as Server 2003.
