Microsoft has released Windows Server Insider Preview Build 17035 to Windows Server Insiders

Server Insiders now have your choice of ISO format or VHDX format. The images are pre-keyed – no need to enter a key during setup.

Also new to Insiders, an early update to the Technical Preview of Project Honolulu. Project Honolulu is a flexible, lightweight browser-based customer-deployed platform and solution for Windows Server management scenarios for troubleshooting, configuration and maintenance. Project Honolulu Technical Preview 1711 Build 01003 is now available to Insiders before the public and is our first update since our initial Technical Preview 1709 released for Ignite.

Symbols are available on the public symbol server – see Update on Microsoft’s Symbol Server blog post and Using the Microsoft Symbol Server. As before, matching Windows Server container images will be available via Docker Hub. For more information about Windows Server containers and Insider builds, click here.

This Server Insider pre-release build will expire on July 2nd, 2018. For the best experience, the Windows Server team recommends a clean install.

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 (127.0.0.1) to access services running in containers on the host
