Microsoft Windows / 10:Windows Update Builds
When the techincal preview got released, it included a "Preview builds" feature. It was supposed to allow you to download new preview builds and directly update to them. However, this feature isn't working as of now. By some registry hacking and deep digging, we were able to get a handful of new buildstrings and even their ESD names, but there's not yet a known way of downloading them. This list is not definitive and will probably grow in the next days.
