Windows 10 SDK preview build 17682 now available for developers

Windows 10 SDK preview build 17682 is now available for developers, matching the latest Windows 10 build available on the Insider Fast and Skip Ahead rings.

Along with a batch of API changes, the latest SDK preview includes the ability to package your apps as MSIX. Though, it's worth noting that MSIX is not currently supported by the App Certification Kit and the Microsoft Store.

Here's a look at all of what's new:

MSIX Support

It's finally here! You can now package your applications as MSIX! These applications can be installed and run on any device with 17682 build or later.

To package your application with MSIX, use the MakeAppx tool.aspx){.nofollow}. To install the application – just click on the MSIX file.

MC.EXE

  • We've made some important changes to the C/C++ ETW code generation of mc.exe (Message Compiler):

  • The "-mof" parameter is deprecated. This parameter instructs MC.exe to generate ETW code that is compatible with Windows XP and earlier. Support for the "-mof" parameter will be removed in a future version of mc.exe.

  • As long as the "-mof" parameter is not used, the generated C/C++ header is now compatible with both kernel-mode and user-mode, regardless of whether "-km" or "-um" was specified on the command line. The header will use the ETW_KM macro to automatically determine whether it is being compiled for kernel-mode or user-mode and will call the appropriate ETW APIs for each mode.

Preview SDK 17682 is now available to download from Microsoft. For the full list of API changes and details on what's new, you can check out Microsoft's full release notes.
