Microsoft Launches Windows 10 16257 Preview SDK

Users can now download the SDK of Windows 10 16257, which launched with the Eye Control feature a week ago. The latest Mobile Emulator is also available.


Last week, rolled out Preview Build 16257. The () release added important new features and has moved through the Insider Program. Microsoft has now released the SDK Preview build 16257 to Insiders. Additionally, the company has sent out a new Module Emulator Insider Preview.

There is some interesting about the Windows 10 16257 SDK. Specifically, Microsoft usually releases an SDK when the next preview release is moving to the Slow Ring. This time, the release coincides with the newest Fast Ring release.

As we reported last week, the most important feature of Windows 10 16257 is Eye Control. Born of Microsoft's first hackathon, the feature helps users navigate Windows with just their gaze.

Among 16257's other features are improvements for Microsoft Edge and Windows Console improvements. Windows 10 emulators allows developers to test their apps within a virtual environment in Visual Studio.

You may remember, Microsoft recently rolled out the finalized SDK for the Fall Creators Update. However, the company will continue to tweak the experience until full launch.

The SDK preview landed alongside the latest Mobile Emulator Insider Preview.


As usual, Microsoft has provided a changelog for the release:

  • Designer fails to render: When viewing the XAML in the Designer Window in Visual Studio, the controls fail to render. This can be resolved by using Visual Studio 2017.3 Preview.
  • Compilation fails on non-Windows 10 platforms (need to see if fixed)
    When building apps on previous platforms, you may get a build error:
