Microsoft is now testing Windows 10 build 16269 for PCs. The new Redstone 4 build 16269.1000 (rs_prerelease.170815-1435) was compiled on August 15, 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. If everything goes right, we can expect Windows 10 build 16271 or build 16272 for Fast Ring Insiders 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.
Recently, the software giant also released cumulative updates KB4034674(1703), update KB4034661(1607), and KB4034660(1511) for Windows 10 devices.
