Windows Server Insider Preview build 17079 is out

Microsoft today released a new Insider Preview of Windows Server. This time it is Windows Server Build 17079. This build is a preview version 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 minor fixed only.

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 Windows Server Build 17074

• In-place OS Upgrade: Customers are now able to upgrade their Windows Server, version 1709 installations to the current preview build using In-place OS Upgrade. This feature is available starting in build 17079. This feature also enables customers to perform build-to-build upgrade of the next released preview build.Running setup.exe, customers should be presented with the option to “Keep personal files and apps”, which causes the migration steps in setup.exe to run and upgrade Windows Server while preserving applications, data, and user settings.

Known issues in Windows Server build 17079

• [NEW] When Hypervisor Code Integrity (HVCI) is enabled, a system may fail to start. On affected systems, firmware locates UEFI runtime services in memory described as Memory-Mapped I/O (MMIO).
• Running nanoserver-insider containers on a Windows Server Core host will fail, and may crash the host.
  As a workaround, you can add “—isolation=hyperv” when running or building the containers such as “docker run –isolation=hyperv microsoft/nanoserver-insider”.

Known Issues with In-place OS Upgrade

(1) Drives that are protected with BitLocker should have BitLocker suspended (disabled) before In-place OS Upgrade, and resumed (enabled) after In-place OS Upgrade.

(2) AD Domain Controllers might not upgrade correctly – please backup any AD DC before applying In-place OS Upgrade.
