Static website generator for Windows?

There are many static website generators for Linux and Mac, most implemented in Ruby or Python: jekyll, hyde, webgen... all of them are best suited for "unixy" operated systems, but what about Windows? Of course, anyone can install Ruby and Python on Windows and use these tools, but I don't find it as usable as in Linux or Mac. I tried googling for it but I don't find any.

I thought about coding simple generator as Powershell script if there are none.

Is there any Windows based solution with similar features as mentioned tools?
