New Windows Server vNext preview coming next week!

Hello Windows Server Insiders!

A new Windows Server vNext preview release is coming next week!

We have a number of features to share with you and can't wait to hear your feedback. Stay tuned!

Please note: Upgrades from earlier Windows Server preview builds are not supported. We encourage all Windows Server preview users to perform a clean install using this new baseline build once available.  

  • While upgrades from earlier Windows Server previews (Build 26525 and older) are not technically blocked by setup.exe, a number of known issues have been identified related to upgrades necessitating a release of a new baseline build for our Server Insider Program.
  • The new baseline build will not be Flighted due to upgrade issues. Flighting support will resume with future preview releases.

How to Download

Registered Insiders may navigate directly to the Windows Server Insider Preview download page.   If you have not yet registered as an Insider, see GETTING STARTED WITH SERVER on the Windows Insiders for Business portal.

Diagnostic and Usage Information

Microsoft collects this information over the internet to help keep Windows secure and up to date, troubleshoot problems, and make product improvements. Microsoft server operating systems can be configured to turn diagnostic data off, send Required diagnostic data, or send Optional diagnostic data.  During previews, Microsoft asks that you change the default setting to Optional to provide the best automatic feedback and help us improve the final product.

Administrators can change the level of information collection through Settings. For details, see http://aka.ms/winserverdata. Also see the Microsoft Privacy Statement.

Terms of Use

This is pre-release software - it is provided for use "as-is" and is not supported in production environments. Users are responsible for installing any updates that may be made available from Windows Update. All pre-release software made available to you via the Windows Server Insider program is governed by the Insider Terms of Use.
