Microsoft missed the bug despite users filing reports in its Feedback Hub, since the number of total reports of file deletion was too low to trigger a quicker response by its engineers.
Users who installed the "Windows 10 October 2018" update complained last week that the process wiped out their user profiles, including documents and photos. It happened to "one one-hundredth of one percent of version 1809 installs", he indicated. At just two days into the rollout when we paused, the number of customers taking the October 2018 Update was limited.
Reports emerged shortly after the release that data loss occurred on some upgraded systems after the upgrade to Windows 10 version 1809.
According to Cable, the company has activated a feature "for users to also provide an indication of impact and severity when filing User Initiated Feedback" to better ensure that serious issues actually end up in front of an engineer.

This includes fixes for system components such as the Windows kernel, graphics and file systems, the wireless networking and peripherals subsystems, along with the JET database engine, Windows Media Player and the Edge and Internet Explorer web browsers among others. Microsoft made no mention of that in the update on the Windows Experience website.
Windows 10 1809 won't be broadly released until early adopters in the Windows Insider program have tested the revised update and provided feedback to Microsoft. Microsoft plans to re-release the new OSes after getting testing feedback.
