This build is the RTM of Windows 10 October 2018 Update.

Data Loss
The original release of this update from 2018-10-02 has a bug that deletes every file in the My Documents, My Music, My Pictures, and My Videos directories when updating from older versions of Windows 10. Back up all data before updating or disable the "Delete user profiles older than a specified number of days on system restart" group policy prior to installation if the updating SKU is Pro.

This update revision was pulled from Windows Update on 2018-10-06.

Microsoft fixed the data loss bug and released a bugfixed version for Insiders on 2018-10-09. It was re-released on Windows Update on 2018-11-13.
