With Windows 10 October 2018 Update OS version 1809 almost reaching its general availability to release to everyone in October 2018, Microsoft is set to sign off a final RTM build sometime in September 2018. As such, the newest Windows Insider preview build pushed by Microsoft to Windows Insiders may potentially be the final RTM (released to manufacturing) build, as such a RTM Escrow build.

The latest build rolled out by Microsoft for rs5_release branch is build 17763. All changes in the build is focused on fixing bugs and under the hood improvement, and does not have any new features or functionality. The build has some known issues though, but if the build becomes the RTM final code, Microsoft can always fix any issues with CU (cumulative updates).

However, do note that a new build 17764 has been published by Microsoft as canary build and as such Windows 10 October 2018 Update v.1809 could be build 17764 or any other builds too.
