Windows 10: October 2018 1809 update deleted my folders and files

October 2018 1809 update deted my folders and files Support and MS Store cannot restore them. Years of important personal health records and financial information is gone. Support does not think any new release will retrieve my files. I cannot get to anyone at Corporate to find out what Microsoft plans to do to make things right and/or compensate for the loss.


What recourse do I have?

I want to confirm the exact same issue as Robert Ziko has reported.

On 03-10 I read there was an update out ran the following updates from Settings > Update & Security > Windows Update:

Feature update to Windows 10, version 1809

Definition Update KB2267602 (Definition 1.27.599.0)

Definition Update KB2267602 (Definition 1.27.595.0)

Definition Update KB2267602 (Definition 1.27.571.0)

Windows Specifications:

Edition Windows 10 Pro

Verson 1809

Installed on 03-10-2018

OS build 17763.1

This is a fairly recent Windows 10 Pro install, not an upgrade for a previous version of Windows. The eventlog was purged after the install of 1809 (some workplaces would call this a security incident).

The C:\Users\kay_h\Documents folder was empty

The C:\Windows.old\Users\kay_h\Documents was removed or didn't exist before

The C:\Windows.old\Users\kay_h\ profile was nearly empty basically only contained some C:\Windows.old\Users\kay_h\AppData\Local data. It does have a NTUSER.DAT with the timestamp of the upgrade tot 1809.

I did try to get the some files back with undelete tooling, without success. I was specifically interested in some VMs but they where very large (>100GB) and the drive had <40GB free. Interestingly there were no deleted files with the time stamp of the update,
possibly the data wasn't deleted but misplaced, moved or lost by some other process then deleting.

Totally unfounded & wild speculation: The C:\Windows.old\ folder was used as a placeholder dir in the update process and someone forgot to prepare or made a type-0 in C:\Windows.old\Users\%username%\Documents folder as a target for file movement.
