Windows 10 build 17126 (10.0.17126.1) info

Windows 10 build 17126 is now going through internal testing. The new Windows 10 Spring Update build 17126 (10.0.17126.1 rs_prerelease.180316-1659) was compiled on March 16, 2018. Recently, build 17125 was also compiled. We’re now getting closer and closer to the RTM build release which might roll out next week.

Windows 10 Spring Update preview build 17123 is now available for Insiders which has added a High-Efficiency Image File Format (HEIF) for Windows 10 and the Photos app.

This new feature leverages modern codecs like HEVC to improve quality, compression, and capabilities compared to earlier formats like JPEG, GIF, and PNG. In addition to traditional single images, HEIF supports encoding image sequences, image collections, auxiliary images like alpha or depth maps, live images & video, audio, and HDR for greater contrast.

Windows 10 build 17123 ISO images are also now available for download. You can download it from the link below. The final Windows 10 Spring Update will release in April for everyone.
