windows 10 (October 2018 update) (version 1809) deleted all my files

Yes, Cindy, MS response posted late last night is here: 

https://support.microsoft.com/en-us/help/4464619/windows-10-update-history

Um - Sorry Jenny - I did allow the upgrade to proceed normally. Seemed OK at first (Chrome works, Outlook has a hiccough) but then Quicken fails utterly. A deep search of C: reveals no .PST or .QDF files exist - only hanging shortcuts. All gone. Lots of noise about this on the forums and in the press.

UPDATE: Version 1809 pulled from Media Creation Tool as of 9:52 PM PST Friday. I think it might be due to this issue since we've heard nothing on it from Microsoft yet. 

Thank you, Greg, for trying to help us track down the exact scenarios this is happening, and for keeping us updated on the status from Microsoft. Now that it has been pulled from the Media Creation Tool website, we can wait for them to address this problem. I just hope that they have a better idea of what happened and why some users were affected and others were not.

Has Microsoft issued any public statements yet, that you have found?

Thanks,

I see that MSFT pulled the October update as of 6Oct2018 (Build 1809).  Just wanted to toss out another similar issue, but different...

While I didn't lose anything in the "My Documents", my entire desktop folder (c:\users\rcurtis\desktop) was gone.  As reported by others, the folder was there, but no contents.  Even looking in windows.old, it was empty, so like others reported, a restore to previous build would not help.

Here's where the difference set in...  I have folder redirection setup to sync profile information stored on a network drive (ref. HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders).  I also don't keep typical profile info stored under 'special folders' (profile based).  My 'documents' are actuall off the root in C:\Documents (not a special folder) and likewiese with Music, Photos, Videos -- each are separate folders off the root.  None of those documents were impacted, nor were any of my redirected folders (obviously), however the contents of my c:\users\rcurtis\desktop folder were.  I did have a backup, but still -- MSFT should have had easily trapped such a glaring flaw, and given the Windows.Old folder/function, how can something like this occur?

I've always been an early adopter to test some of the applicaitons I have to support (where we've been bit in the past  -- 2017 Fall Creator build notably -- given the .NET issues), but I have never experienced issues where personal files vanished.  Obivously, MSFT is not going to be able to magically restore the personal documents of the many, many folks affected, so it will be interesting to see how MSFT responds...

Backup, Backup, Backup.  I've been very frustrated adding OneDrive. It caused havoc with my primary offsite backup. Now have tamed it.  

Reading the articles about lost files and not trusting OneDrive as 100% independent of issue I paused or disabled.

Mr Ziko. - Have you checked for articles or blogs with same issue and a resolution such as a File Recovery backup.  Windows probably over wrote docs folder first.

Don't know Mac but would probably agree with you.

PLEASE - everyone. Backup your files now, before you get the surprise update with issues Mr Ziko experienced.

Good luck Robert. Hope its all there. If so drag whole My Docs folder to OneDrive and GoogleDrive
