Announcing Windows Server Insider Preview Build 17079

By / Software Engineer, Windows and Devices Group

Hello Windows Insiders!

Today we are releasing Windows Server Insider Preview Build 17079 to Windows Server Insiders. This build is a preview build of the next Semi-Annual Channel release of Windows Server. For more information on the Semi-Annual channel, please see the Windows Server Semi-Annual Channel overview

What’s New in Build 17079 for Windows Server

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.

Please refer to the Known Issues section below for additional information.

Please indicate what build number you are providing feedback on.

Known issues with 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.

Terms of Use

All pre-release software made available to you via the Windows Server Insider program are governed by the Insider Terms of Use, which takes precedence over any license agreement that may be in the product.
