Today we are pleased to release a new build of the Windows Server vNext Long-Term Servicing Channel (LTSC) release that contains both the Desktop Experience and Server Core in all 18 server languages, as well as a new build of the next Windows Server Semi-Annual Channel release in English. In addition, a new build of Microsoft Hyper-V Server is included with this build.
In each preview release, there are two major areas that we would like you to try out:
In-place OS Upgrade (from Windows Server 2012 R2, Windows Server 2016 or a previous preview build). Build-to-Build upgrade is also supported.
Application compatibility – please let us know if any server roles or applications stops working or fails to function as it used to. Please report any issues you find.

[NEW] Server Core App Compatibility FoD Preview 17713 for Windows Server Core is not available due to a blocking installation failure.
On a recent preview release of Server Core, the Advanced Query Syntax (AQS) parser may fail if the default language and locale are changed to something other than US English. If the AQS parser is not working, search functionality in Exchange does not work.
Creating or modifying environment variables by using setx fails on a system running in a Nano Container (that is, Nano Server as a container image). On an affected system, setx requires a specific path in the registry, HKCU\Environment\, to exist by default. You can work around this issue by changing where the variable is stored in the registry, or you can add the expected registry path before executing setx commands. To specify that the variable be set for system-wide use in HKLM rather than in HKCU, the default, add the /M switch to a setx command. To instead add the expected registry path, run reg add HKCU\Environment before executing setx commands.
The Virtual Machine Management Service (VMMS) may experience an error, APPLICATION_FAULT_INVALID_POINTER_READ, in Cluster Manager.
Editing or creating policies for AppLocker can cause the MMC snap-in to crash when generated rules for a packaged app.
