7:24 pm in Build 17623, Microsoft Tech Community, Windows Server 2019, Windows Server Insider, WS2019 by Wim Matthyssen

Yesterday Microsoft announced that Windows Server 2019 would be generally available in the second half of 2018, together with System Center 2019. As expected, this next-gen (vNext) Server OS is built on top of Windows Server 2016 and will focus on the following main areas: hybrid, security, application platform and hyper-converged infrastructures. Good to know is that Windows Server 2019 is a Long-Term Servicing Channel (LTSC) release, which means it will have 5 years of mainstream support and 5 years of extended support.

Whit this announcement Microsoft also released the first preview build (17623) of Windows Server 2019 LTSC to the public, which contains both the Desktop Experience as well as the Server Core edition in all 18-server languages.

To get started with the download of this Preview build, you need to be a member of Windows Server Insider program. If you are not yet registered for this Insider program, you can do so over here. Keep in mind that you can sign up with an organization or a personal account.
