General Scenario Highlights
Developers and Containers:
Windows Subsystem for Linux (WSL) is available on Windows Server
Delivery Optimization is available for Windows Server
Delivery Optimization has been the main downloader of Windows Update and Windows Store content since the Windows 10 Anniversary Update, providing faster and more reliable downloads. Starting in the latest builds for Server, Delivery Optimization is now the downloader used by Windows Update on Windows Server.Delivery Optimization can also provide Peer-to-peer bandwidth optimization between Windows Server machines. To enable peer-to-peer downloads open Settings -> Update & Security -> Advanced Options -> Delivery Optimization and turn ON the toggle to “Allow downloads from other PCs”.
For more information on Delivery Optimization including configurations you can set via group policies or MDM policies please visit http://aka.ms/waas-do
How to Download
The latest Windows Server build and matching symbols are available for download here. Matching Windows Server container images will be available via the Docker Hub. For more information about Windows Server containers and Insider builds, please visit http://aka.ms/containers/insiders.
The following keys are available for unlimited activations of Windows Server. These keys may be used throughout the pre-release cycle.
NOTE: If you signed up for Windows Insiders for Business using an AAD account, there is a temporary issue with access to the Windows Server Download page using AAD accounts.

It’s all about your feedback!
Use the Feedback Hub app to provide feedback on Windows Server builds. Feedback Hub comes pre-installed on Windows 10. Register a Windows 10 device with the Windows Insider or Windows Insider for Business programs. Open the Feedback Hub application. Choose the Server category and then the appropriate subcategory for your feedback. Please indicate what edition and build number you are providing feedback on. The Feedback Hub app cannot scan a server for diagnostic information, however you may manually attach screenshots or other files to your feedback entry.
We encourage you to visit the Windows Server Insiders space on the Microsoft Tech Communities forum to collaborate, share and learn from experts.
The expiration date for this server preview build is 12/4/2017.

Windows Subsystem for Linux (WSL) is available on Windows Server
- Windows Subsystem for Linux (WSL) is now available on Windows Server along with a compliment of Linux distributions.
- Test WSL on Windows Server. WSL runs unmodified Linux (ELF64) binaries natively. With the additions of WSL you can run node.js, Ruby, Python, Perl, Bash scripts or other tools that expect Linux behaviors, environment, or filesystem-layout, the ability to install and run Linux with WSL expands the tools at your disposal on Windows Server.
- At this time, WSL does not support persistent Linux services (such as daemons and jobs) as background tasks. To enable WSL and install a Linux distribution, see Enable the Windows Subsystem for Linux and Install a Linux distribution in the Windows Server 2016 Installation Guide on GitHub.
- Read more in this blog or follow the installation guide to try it out.

Known issues
- The background tasks infrastructure service (Bisrv.dll) may cause a system crash because of a null class pointer read error (0xC0000005) or a failfast corrupt list entry (0xC0000409) during a Distributed Component Object Model (DCOM) launch, or because of a critical process bug check (error code 0xC0000409, bug check 0xEF) in the host process for Windows services (Svchost.exe).
- Calling into the firewall service may hang: Apps that call into the firewall, such apps that use networking, may become unresponsive until the user reboots because of an application hang end-task error (0xCFFFFFFF) in the Windows firewall API library (FirewallAPI.dll), which occurs when the library is blocked on an advanced local procedure call (ALPC) port while attempting to diagnose a connection failure and retrieve information.
- Cluster Sets: A couple of key functionalities to enable end-to-end testing of Cluster Sets scenarios are not present in this build, so defer all evaluation of this scenario to a future build.
- Bugcheck during volume creation: A stop error may occur during volume creation in a cluster. The recommended workaround is, after restarting the computer, to delete the volume and try creation again.
- Bugcheck during volume repair: A stop error may occur during volume repair in a cluster. The recommended workaround is to restart the computer. No corruption or data loss is expected.
