Microsoft yesterday released Windows 10 SDK Preview Build 17733, which developers can use in conjunction with Windows 10 Insider build 17733 or higher. As a reminder, the last Windows 10 RS5 build (17738) was released earlier this week with a small list of bug fixes and improvements.
This new SDK Preview build brings the usual bug fixes and under development changes to the API surface area. As usual, you can download it from the developer section on the Windows Insider website. A full list of all the API Changes can be found on the Windows Insider blog, but for now, nothing much else has changed. Microsoft also continues to list the same new features in each release, including MSIX Support, and changes to MC.EXE.
This has been a pretty busy week for the Windows Insider team as we saw new 19H1 and RS5 builds for Windows 10 (including one for HoloLens), as well as a new Windows Server 2019 preview build. The next major update for Windows 10 is now almost fully baked, but the pace of new preview builds probably won't slow down until later this Fall.
