Following the rollout of Windows 10 Insider PC build 17035 last week, Microsoft has just released the Preview SDK build 17035 that developers can now use in conjunction with the latest Redstone 4 build. As usual, the new SDK can bee downloaded from the developer section of Microsoft’s Windows Insider website.

The Preview SDK Build 17035 brings some bug fixes, API changes as well as the inclusion of C++/WinRT headsets and cppwinrt complex. You can learn more about this latest addition below:

The C++/WinRT headers and cppwinrt compiler (cppwinrt.exe) are now included in the Windows SDK. The compiler comes in handy if you need to consume a third-party WinRT component or if you need to author your own WinRT components with C++/WinRT. The easiest way to get working with it after installing the Windows Insider Preview SDK is to start the Visual Studio Developer Command Prompt and run the compiler in that environment. Authoring support is currently experimental and subject to change. Stay tuned as we will publish more detailed instructions on how to use the compiler in the coming week. The ModernCPP blog has a deeper dive into the CppWinRT compiler. Please give us feedback by creating an issue at:

In addition to the Windows 10 SDK Preview build 17035, Microsoft also released the Windows Server Insider Preview Build 17035 yesterday, which is the first Redstone 4 build for the server operating system. This latest build brings a new Technical Preview of Project Honolulu, Microsoft’s new browser-based tool for server administration.

Windows Insiders can download the Preview build 17035 for Windows Server on this page and learn more about everything that’s new below:

What’s New in Build 17035 for Windows Server

  • Storage Spaces Direct (S2D) is enabled. Storage Spaces Direct is the foundation of our hyper-converged solution and we’re continuing to evolve it. In this preview build we not only brought it back, but we’re adding some new and important updates to it – such as support for Data Deduplication, a commonly requested feature for Storage Spaces Direct and ReFS. Starting with this build, Data Deduplication will reduce the data footprint by up to 50%.
  • Developers can now use localhost or loopback ( to access services running in containers on the host

NOTE: Please manually Refresh your browser (F5) on first launch if upgrading from version 1709.

  • Remote Desktop: With the remote desktop tool in the Server Manager solution, you can connect to your machine to complete scenarios that are not yet supported natively in Honolulu. If you want to configure a feature that has no GUI tool, connect with Remote Desktop and open PowerShell!
  • Windows 10 Client Management: You can now add Windows 10 client machines as connections in Honolulu, and manage them with a subset of tools in the “Computer Management” Solution
  • Switch Embedded Teaming (SET): Short of SCVMM, there was previously no GUI experience to configure Switch Embedded Teaming (SET), a new feature released in Windows Server 2016. You will find this feature in the Virtual Switches tool.
  • Data grid performance improvements: We have updated the grid in the Certificates and Events tools to a more performant control which is able to handle large datasets without a loss in performance. In the next release, it will be updated across all tools. In the Events tool, the data is streamed in as it loads, which can lead to a shorter loading time than the in-box tool when working with channels that contain many events.
  • Removed: LAPS in Service mode: We have removed the ability to use LAPS when Project Honolulu is deployed as a Server service.  You may still use LAPS when you install Honolulu on Windows 10.

This is pretty good stuff for developers and Windows Server users, but what about new Windows 10 PC builds, you may ask? According to Windows Insider chief Dona Sarkar, Fast Ring Insiders may well get a new Redstone 4 build as soon as today. Stay tuned to OnMSFT if you don’t want to miss the new bits.
