Java™ at Microsoft

Java at Microsoft spans from Azure to Minecraft, across SQL Server to Visual Studio Code, LinkedIn and beyond! We use more Java than one can imagine.
The Microsoft Build of OpenJDK is a new no-cost long-term supported distribution and Microsoft's new way to collaborate and contribute to the Java ecosystem.

Go to AdoptOpenJDK 11 (LTS). (AdoptOpenJDK 11 LTS is the recommended OpenJDK distribution because it's continuously tested with Polarion and offers long-term support.) Select the HotSpot implementation for Windows x64 and download the JDK.zip file. Extract the downloaded zip file into, for example, C: Program Files Java. OpenJDK 11 Windows 64-bit Release date November 01, 2018. Download (181.24 MB) jdk-8u191-x64 MSI. Windows Installer. Windows Installer Release date February 05, 2018.

Microsoft is proud to have contributed the Windows on Arm port in 2020 as well as having made major contributions to the macOS M1 port.

Eclipse Adoptium

Microsoft has a long history of supporting developer ecosystems and we are pleased to extend this support to the Java ecosystem by joining the Eclipse Adoptium Working Group as a strategic member.
