Today, Microsoft announced they have released Windows 10 SDK Preview build 17125 to developers. As usual, this build is meant to be used with any consumer-facing Windows Insider build and supported Windows operating system. There is not much new with this release, but it does bring bug fixes and other under development changes to the API surface area.
You can check out what is new with this build by checking Microsoft's website here. Please be aware there are some new MIDL keywords and several APU updates and additions in this build. The latest Preview SDK also only works with Visual Studio 2017, which is available to download here.
As is routine, those interested in downloading can find this new build now by heading to the developer section of the Windows Insider website. Microsoft is actively looking for feedback via the developer forum, and also reminds users to head to the Windows Platform UserVoice to submit new feature requests.
