Microsoft Fixes and Explains Lost Files Issue with Windows 10 Version 1809

10 October 2018

The Windows 10 October 2018 Update (version 1809) was made available on October 2nd but hadn't yet been pushed through Windows' automatic update system. You create "D:\documents" and change the location of the files known folder from the original "old" location c:\users\username\documents to D:\documents. Some issues included minor task manager bugs, but a showstopper bug that was deleting user files meant that the company had to pull the update out of distribution completely.

It isn't ready to begin delivering the fixed 1809 update to most users yet (a test version is rolling out to its Slow and Release preview rings first), but a change that's already noticeable is in its Windows Insider Feedback Hub.

#WindowsInsiders If you've run into the "missing files after update" issue for 1809/October 2018 Fall update, please call our support line.

Known Folder Redirects gives users options to move the classic Windows folders Desktop, Documents, Pictures, Videos, and so on to another location. During this process the system prompts the user and asks if they would like to move the files to the new location. "Based on feedback from users, we introduced code in the October 2018 Update to remove these empty, duplicate known folders".

We have fully investigated these issues and developed solutions that resolve all three of these scenarios, so the "original" old folder location and its contents remain intact.
If the files were not moved and the October 2018 Update is installed the original "old" folder was deleted including the files in that folder.

As Microsoft's John Cable explains in a post on Microsoft's Windows Blog, the problem was with the "Known Folder Redirection" feature.

Microsoft is also updating the Feedback app in Windows 10 to enable a new feature that would allow Insiders to provide an indication of impact and severity when filing feedback. Anyone impacted by the issue can contact Microsoft Support to get assistance in attempting to recover the lost files- the company's retail stores with support services are also offering help.

For those who are affected, they should call Microsoft at +1-800-MICROSOFT or find a local number in your area.
