Windows Server Insider Preview build 17035 is out

Microsoft today released a new Insider Preview of Windows Server. It is Windows Server Build 17035. This build is the first preview build of the next Semi-Annual Channel release of Windows Server. Here is the change log.
The Insider Preview program for Windows Server allows customers to try out all the new features of the upcoming OS and provide feedback on them to Microsoft. The release comes with a number of fixed. The official change log comes with the following highlights.

• 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

There are some known issues in this release:

• [NEW] The base filtering engine (BFE) service may fail to start, which prevents the Windows Defender firewall (MpsSvc service) from starting.
• A system crash may occur because of a kernel security check failure (bug check 0x139) from a corrupt list entry in a deferred free pool.
• An application may crash because of a heap entry corruption error (0xC0000374) in the health attestation configuration service provider (CSP) library (Hascsp.dll).\
• Testing of the Windows core may fail because of a timeout while attempting to load the test libraries.
