Windows Server 2019

Windows Server 2019 is a version of the server operating system by Microsoft, as part of the Windows NT family of operating systems. It was succeeded by Windows Server 2022 in August 2021.

Development and release
Windows Server 2019 was announced on March 20, 2018, and the first Windows Insider preview version was released on the same day. It was released for general availability on October 2, 2018.

On October 6, 2018, distribution of Windows version 1809 (Build 17763) was paused while Microsoft investigated an issue with user data being deleted during an in-place upgrade. It affected systems where a user profile folder (e.g. Documents, Music or Pictures) had been moved to another location, but data was left in the original location. As Windows Server 2019 is based on the Windows version 1809 codebase, it too was removed from distribution at the time, but was re-released on November 13, 2018. The software product life cycle for Server 2019 was reset in accordance with the new release date.
