Microsoft released build 14385 to Fast Ring Insiders just two days ago, but it looks like we could have a new build arriving as soon as tomorrow.

Dona Sarkar, the Head of the Insider Program, has confirmed on Twitter that she is using a newer build than the one that Insiders currently have access to – and it could be this very build that we see released next, provided that no major issues are discovered.

As reported by, build 14388 could be released just three days after the last build. As with most of the recent builds, it is likely that this build will include bug fixes and performance enhancements, as we are just weeks away from the Anniversary Update rolling out to millions of Windows 10 users across the world – on both Windows 10 Mobile and PC.

A build for the current production release of Windows 10 could also be releasing tomorrow, and that is build 10586.494. This is a small update and will include fixes for reported issues by users on the release builds.
