Getting *anything* added to Windows is a big task, so it's a reflection of the popularity and support for Python that's growing within Microsoft that we were able to make this happen. That's due to every contributor, both to the core runtime and the ecosystem. I hope this will only help us improve the availability of Python for users and make it an easier choice for dev tasks in the future.
