Announcing Windows Server Insider Preview Build 16237

Hello Windows Insiders!

On June 15th we announced some very exciting news: Windows Server will now have more frequent releases providing customers who are innovating quickly an opportunity to take advantage of new OS capabilities at a faster pace, both in applications – particularly those built on containers and microservices – as well as in the software-defined datacenter.

Today we are very excited to be releasing the first Windows Server Insider Preview to Windows Insiders: Build 16237. To access to the latest Windows Server preview release, register at the Windows Insiders for Business program or the Windows Insider Program.

Windows Server Datacenter Core and Standard Core editions are headless operating systems and are best managed remotely. For more information, please refer to Configure a Server Core installation of Windows Server with Sconfig.cmd. Updated remote administration information will be provided with future Insider releases.
