Windows 10 RedStone3 (RS3) Builds Changelog

UPDATED on May 04, 2017: Addition of Windows 10 Insider Preview build 16188.

After releasing Windows 10 Creators Update build 15063 version 1703 to public, Microsoft has once again started providing new testing builds of Windows 10 to Windows Insiders group.

The new Windows 10 Insider Preview builds come from a new development branch called RS3 (RedStone3), so all new Windows 10 builds releasing after Creators Update will be referred as Windows 10 Redstone 3 builds.

When Microsoft will finalize the RTM build of RedStone3 in future, it’ll be given a name similar to November Update, Anniversary Update and Creators Update but that’ll take some time.

The final Redstone 3 build will be released to public in September or October 2017 as per official announcement from Microsoft.

In this article, we’ll list all changes, improvements and new features found in newer Redstone3 builds released after Windows 10 Creators Update public build 15063.

It’ll help you in understanding what changes and new features will become a part of the upcoming version of Windows 10 operating system.
