When upgrading to Windows 10 October 2018 Update, the contents of the libraries are permanently and without any warning deleted.
Installing a large-scale Windows update October 10, 2018 Update (version 1809), released in early October 2018, may result in permanently deleting personal files of users on some computers. How widespread the problem is is unknown, but this topic is vigorously discussed on the web.
According to reports from affected users, the problem manifests itself when upgrading from Windows 10 Fall Creators Update to October 2018 Update via Windows Update. At the same time, the contents of the Windows libraries — documents, images, music, and video — are deleted permanently and without any warning. Apparently, the problem is due to the fact that Windows does not automatically create a backup copy of the deleted files and does not include copies of the content stored in libraries in the Windows.old folder, which allows you to return to the old version of the OS if the new user didn’t work with something.
“It happened to one of my computers. I removed the hard drive and connected it to the host PC via a SATA adapter to USB 3. It turned out that the media was almost empty. I have backups, so it did not become a problem. The only thing that remains on my disk is the Windows.old folder and the regular Upgrade folder, ”theuser said under the pseudonym SonicHyuga.
Microsoft representatives did not comment on the situation. While the only way out is to create backup files before installing Windows 10 October 2018 Update.
