After months of development and testing, the Windows 10 October 2018 Update has come and gone ... Another failure in the history of Windows 10 failures 
Once again, it turned out that Microsoft's thousands of Insiders weren't enough to report all the Windows problems. This time the problem was significant: the update deleted some users' personal files.
So, 48 hours after the new version was officially released to the public, Microsoft pulled the Windows 10 October 2018 Update to investigate the problem.
As we have mentioned in previous posts, there seems to be a very basic problem with the Windows testing process.
Microsoft relies primarily on the Windows Insider program to fix bugs in the Windows operating system. So with each new major update, new features are developed and added, which are then tested by Insiders. Most of the bugs in these new features are usually noticed by Windows Insiders and fixed by Microsoft before the update is released to the general public.
But because there are issues that only affect some users, the company's developers seem to be working on the bugs that have the most red flags. The Feedback Hub is the application used by Windows 10 users and Insiders to report bugs and suggestions to Redmond.
At this point we will report the news: The data deletion problem was reported to Microsoft by some Insiders 3 months ago, as reported by Rafael Rivera on Twitter.
If you simply open the Feedback Hub and search for the term “documents deleted.” You will see many reports from Insiders whose files were automatically deleted after installing the update.
Because these issues are not widespread, most of these Insider reports are “overshadowed” by other much more “important” ones,
“Make File Explorer look more modern” or “Add Acrylic to File Explorer”.
While the above are valid reports of Insiders' wishes, they often prevent Microsoft from noticing real issues, and this is a core problem of the Windows Insider program.
Things are getting even worse, as Microsoft has cut back on independent testing a few years ago, and relies mainly on Insiders to test its software.
But everything shows that the Feedback Hub is not very capable of addressing issues from millions of users, especially when the same application is used mainly by fans of the operating system who ask for new features and colors. Critical issues are not only buried under the acrylic paint of File Explorer, but also lead to disasters like the one that many experienced with their files after installing the new version.
