Hello Farzana Mustafa,
I’ve checked the Microsoft Learn page you referenced, and at the moment the latest available build listed under OpenJDK 17 is 17.0.17 LTS, not 17.0.18. The download table shows packages for Linux, macOS, and Windows across x64 and ARM64 architectures, but the new GA release you mentioned (17.0.18, January 20, 2026) has not yet been published on the Microsoft Build of OpenJDK download portal. This means the documentation is lagging behind the upstream OpenJDK release cycle.
Microsoft’s Build of OpenJDK follows upstream GA releases but there is typically a short delay before binaries are tested, signed, and posted. The official download page is updated only after Microsoft has completed validation and published the packages. Until then, the page will continue to show 17.0.17 as the latest supported release.
If you need 17.0.18 immediately, you can obtain it directly from the upstream OpenJDK project (Adoptium or Oracle builds), but if your environment requires the Microsoft Build of OpenJDK specifically—for example, for Azure workloads or enterprise compliance—you will need to wait until Microsoft publishes the updated binaries and updates the Learn documentation.
The best practice here is to monitor the official Microsoft Build of OpenJDK GitHub repository and the Learn download page. Microsoft usually posts the updated binaries within days to weeks of the upstream GA. Once published, the links under the OpenJDK 17 section will change from 17.0.17 to 17.0.18, with updated .sha256sum.txt and .sig files for verification.
In short, the link cannot be updated yet because Microsoft has not released their signed build of 17.0.18. You should continue to check the Learn page and GitHub release feed; once Microsoft completes validation, the download links will be updated automatically.
I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!
Domic Vo.
