1. Register

You have two registration options:

  1. Register your organization account (recommended)
    Registering in the Windows Insider Program with your organization account in Azure Active Directory (AAD) lets you and your colleagues submit feedback on behalf of your organization and help shape Windows to meet your specific business needs. Registering with your organization account requires Windows 10 Version 1703 or later. If you do not have an AAD account, find out how to get an Azure Active Directory tenant.
  1. Register your personal account
    Use the same account that you use for other Microsoft services. If you don’t have a Microsoft account, it is easy to get one. Get a Microsoft account.

2. Install

Once you are registered, go to the Windows Server Insider Preview page and download the current build. Matching debugging symbols are also provided. Windows Server builds are made available for you to download and install at your discretion. Microsoft will not automatically install newer builds on your servers. Containers are available via Docker Hub. For more information about Windows Server containers and Insider builds, please visit Windows Containers Documentation.

When new builds are available, announcements will be posted in the Windows Insider Program blog, the Windows Server blog, Windows Server Insiders forum and the announcements section of the Feedback Hub App1.


3. Engage

Provide feedback using the Feedback Hub App1. Select the Server category and appropriate Subcategory for your feedback. Add attachments as appropriate. Be sure to include the build number that you are providing feedback on. When you register with your AAD account, you can also search in the Hub to see feedback from other Insiders in your organization. Feedback per organization is only viewable by Microsoft and the users registered under your company’s domain in AAD. Find out how to provide constructive feedback.

Engage with the Windows Server Insider Tech Community to deepen your connections with the IT Pro community, collaborate and learn from experts, and more quickly resolve critical issues.

Storage Spaces Direct (S2D)

In this preview build we continue to expand and simplify the hardware for Storage Spaces Direct. SCSI Enclosure Services (SES) is no longer required for Storage Spaces Direct to be compatible, this unlocks a breath of new hardware which was not capable of running S2D. Storage Spaces Direct now also supports Persistent Memory (aka. Storage Class Memory), this unlocks a new class of extremely low latency storage which is incredibly interesting in particular as a caching device. Storage Spaces Direct now also supports Direct-connect SATA devices to AHCI controller, again this will expand the hardware ecosystem compatible with S2D as well as unlock a new class of low cost hardware. In this preview we have also enabled the Cluster Shared Volumes (CSV) Cache is enabled by default, which delivers an in-memory write-through cache that can dramatically boost VM performance.

Failover Clustering

In this preview we have introduced enhancements to Azure enlightened Failover Clusters, with enhanced eventing on host maintenance events and nodes about to be in host maintenance are excluded from placement. By making high availability software running inside of an Azure IaaS VM be aware of maintenance events of the host, it can help deliver the highest levels of availability for your applications.

Storage Spaces Direct (S2D)

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%.
