How to Recover Files Deleted Due to Windows 10 October 2018 Update

Microsoft releases two major Windows 10 updates each year that bring a host of new features and refinements to improve system performance, productivity, and stability. However, a recent Windows 10 October 2018 update (version 1809) turned out to be a nightmare for many users.

Several Windows 10 users reported that documents and important files from their user profiles went missing after installing the update that was rolled out in the first week of Oct 2018.

An agonized Windows 10 user who lost several critical files after upgrading to Windows 10, version 1809 update, wrote following on the Microsoft’s support forum:

I have just updated my windows using the October update (10, version 1809) it deleted all my files of 23 years in amount of 220gb. This is unbelievable, I have been using Microsoft products since 1995 and nothing like that ever happened to me.

Files were located at C:/Users/rober/Documents/

This location is still present, with no files. All of files deleted.

I am extremely upset. Not sure what to do….please let me know.

Microsoft has confirmed the issue with a note on their support site that says,

“We have paused the rollout of the Windows 10 October 2018 Update (version 1809)* for all users as we investigate isolated reports of users missing some files after updating.”

However, a tweet from Rafael Rivera (MVP) reveals that Microsoft overlooked the issue.

See the below screenshot of the reports posted on Microsoft’s Feedback hub.

As a precaution, Microsoft has advised the affected of the downloaded version 1809 of Windows 10 Oct update to minimize use of their devices immediately. If you have manually downloaded the update, don’t install it and wait for the new update to arrive.

This is a timely advice because if you continue to use an affected PC, you may overwrite the deleted data beyond the scope of recovery that may otherwise be possible with a data recovery software.

Further, in one of the recent posts on Windows blog, Microsoft’s John Cable briefly explained the reasons behind this software glitch. He mentioned that the problem was with the ‘Known Folder Redirection (KFR)’— a tool used to store the files destined for folders like Desktop, Documents, Videos, Pictures to a different location such as a folder on another volume.

The Windows 10 1809 October 2018 update was introduced with a new code to remove empty and duplicate known folders. The change got combined with another change in the update sequence and resulted in deletion of the original (old) folder location and content, instead of deleting empty or duplicate folders.

Microsoft has confirmed that the issue is now fixed and it will soon re-release the official Windows 10 October 2018 update after further validation.

Microsoft has further asked users to get in touch with its support team to help resolve the issue.

Here’s How to Get Back Your Deleted Files after Windows 10 October Update

While it’s not guaranteed, but users in isolated forums have reported that data recovery software with deep scan* utility did help them recover a significant volume of their missing data that was deleted after the Windows 10 (version 1809) October 2018 update.

Microsoft MVPs like Greg Carmack have recommended trying out data recovery software as the first solution to get back missing files without further damaging or overwriting them. And technically, that’s the only secure way you can get access to your deleted files with minimum system and disk usage.

*Deep Scan thoroughly inspects every individual sector on a storage drive for traces of lost and deleted data based on unique file signatures. Thus, deep scan significantly improves the chances of deleted and lost data recovery.

Again, the probability of recovery depends on how promptly you implement a data recovery software and how often did you use your PC after losing the data.
