Microsoft is now testing Windows 10 build 16268 for PCs. The new Redstone 4 build 16268.1000 (rs_prerelease.170811-1546) was compiled on August 14, 2017. In addition, the company also compiled mobile build 10.0.15243.0 on August 12.
The Windows Insider team has confirmed that they hit a rollback bug with an insider build candidate. As a result, there will be no insider build release until next week.
Previously, Microsoft released the Fall Creators Update build 16257.0 and Windows 10 Redstone 4 build 16257.1000 to Fast Ring insiders. The builds were released with new features, bug fixes, and improvements.
