Windows 10 build 17133 Slow ring

Microsoft is now rolling out Windows 10 version 1803 (build 17133) for PCs enrolled in the Release Preview ring of the Windows Insider Program ahead of the April 10 official release.

Although there are not new features and changes with this rollout, it’s still an important milestone, because it signals that the new feature update — dubbed Spring Creators Update — is now finalized and stable to install it on your primary machine.

However, the update will only arrive to some testers on April 4, Microsoft notes that full availability of Windows 10 build 17133 in the Release Preview ring will happen on April 9, 2018.

If you’re unfamiliar, the Windows Insider Program allows developers and enthusiasts to get early access to upcoming features and enhancements using the Fast and Slow ring levels. In addition, there is third level, called the Release Preview ring, which unlike the first two rings, it’s meant to test system, apps, and driver updates. However, Microsoft also makes feature updates available through the Release Preview, because each major update must pass through every ring.

Windows 10 version 1803 is expected to launch on April 10, but if you can’t wait, you can enroll your device in the Release Preview to download build 17133, which is the final version.

You can check the complete set of improvements for Windows 10 Insider Preview build 17133 at the Windows Blog. In case you missed it, you can read all the changes for Windows 10 build 17128 in this article.
