One of the most critical bugs in Windows 10 October 2018 Update (version 1809) causes an unexpected removal of user files during the upgrade.
While Microsoft is yet to comment on this issue, there’s a growing number of users reporting the same problem, which apparently leads to files stored in libraries to be deleted when the new OS feature update is installed.
For the time being, it’s not yet clear why and who is affected by the glitch, but judging from user reports, there’s pretty much no way to recover the lost data.
This happens because as it turns out, Windows 10 doesn’t move the files to a different location or store them in a backup, but actually deletes them entirely for a reason that’s yet to be determined.
Fortunately, despite no straightforward workaround available at first, it looks like you can get back the lost files using data recovery software. How efficient these apps are, however, depends on a series of factors, including the number of file operations (read and write) you’ve made after you installed the October 2018 Update.
This means that you shouldn’t do anything after noticing that your data is gone, and you are strongly recommended to run the file recovery applications as soon as possible.
How to get back your data
While there’s no guarantee that 100 percent of all your files would be recovered, one of the apps that appear to be effective is called Recuva.
Available free of charge and even with an ad-free version from Softpedia, Recuva scans your hard drives for deleted files and lets you recover them.
As I said earlier, it all depends on several factors and there’s absolutely no promise that all your data will be recovered, but it’s pretty much the only thing you can do in this regard.
After downloading Recuva, launching a file recovery task is pretty easy. The program comes with a built-in wizard that guides you throughout the entire process, and one thing that I recommend doing is pointing specifically to the location where the lost files were previously located.
In other words, don’t let Recuva scan all your drives for all your data – this only takes more time and could have mixed results. Try to scan only the locations where you know that your files were stored, so efficiency in this case could be even higher.
Also, if you have only certain type of data, like audio files, make sure you select this during the wizard. This way, Recuva won’t look for all file formats, but only for audio, and once again, this can help recover more data.
One suggestion that some people offer on support forums is to try to go back to the previous Windows version and see if files are restored. DON’T DO THIS!
Not only that your lost data isn’t there, pretty much because as I said earlier, Windows doesn’t include them in the image that it creates for downgrading, but it also makes it more difficult to recover the files if the operating system is reinstalled.
The file recovery process can take anywhere from a few minutes to several hours, so you better let it complete without a system reboot. Also, try not to work on the computer during the whole time if this is possible.
Without a doubt, this would be the perfect moment for Microsoft to step in and tell us what exactly happens on these computers, especially because the bug leads to critical data loss. It’s not yet known how widespread the bug is, but if you decide to upgrade to the October 2018 Update, you should create backups of your data before anything else.
