Vole temporarily halted the rollout of its October 2018 update for Windows 10 (version 1809), writing in a page dedicated to the update that it would "investigate isolated reports of users missing some files after updating".
Microsoft had to pull the update days after its release because of a data loss issue that impacted some devices. If the file from a compressed archive is being moved, it would silently fail and won't even write the file, which, in effect, deletes the file from the archive and from all existence.

The good news for non-insiders is that the update doesn't appear to be enforcing itself on anyone, so if you do get offered it, you can (and probably should) ignore it until whatever mess Microsoft is making is finally sorted.
Previous versions of Windows 10 would prompt the user for an action such as replacing the original file with the new copy or skipping it.

Comments confirm the assumption: the issue affects only the built-in Zip functionality of Windows 10 version 1809 and not that of third-party application. "Pretty nasty bug since you can accidentally overwrite a file and have no way of getting it back", a user wrote on Reddit. After it had pulled the problematic update for deleting the files of a few users, some Insiders are reporting that the supposedly fixed version of the update is again riddled with frightening errors.
The primary issue revolves around the prompt which should technically appear during the process of un-zipping a file on Windows 10; however, it does not, leading to data loss.More news: Ryanair faces backlash over racist incident on flight
