hey,
It is not actively worked on at present no, I'd consider comissioned work to get it done but without that I do not currently have piles of motivation to take on windows support. I'd love it and I suspect its not a huge pile of work but do not have the cycles for it. I'd also gladly assist community in creating that supported platform.
Already all tests are run on windows and they pass - though I know for a fact some paths are assuming unix for example, fixiing those might get you going. The main hurdle for me is in packaging on windows which I know nothing about
