And now a ZIP file bug also causes data loss in Windows 10 October 2018 Update

It sure looks like Microsoft has a massive problem with the quality control of its Windows 10 updates. Windows 10 October 2018 Update had to be pulled shortly after launch due to a data loss issue with redirecting folders, and now news hit the web that there's also an issue with the operating system's built-in archive manager.

gHacks reports various reports on Reddit and other Internet forums suggest there's something broken with the the copying and unzipping feature of Windows 10's built-in ZIP functionality:

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. Windows 10 version 1809 does not prompt according to reports but overwrites automatically in the selected destination folder.

Another report, this time from a thread on Ask Woody, suggests that it may also happen that the same operation fails silently by not overwriting files at all and not prompting users about it.

A third report on Reddit suggests that drag and drop operations from compressed folders to others appear broken as well. The copy "appears" to happen but when the user checks the files in the destination folder, files have not been updated.

At the moment, Microsoft has not issued a response about this matter.
