Windows 10 Version 1809 Suffers from Yet Another Data Loss Bug

Posted on October 23, 2018 by Paul Thurrott in Windows 10 with 77 Comments

Windows 10 just can’t stop deleting users’ data. Redmond, Hello? Anyone home?

As I assume most readers know, all isn’t well with Windows 10 these days: Windows 10 version 1803 was delayed for weeks when a major software flaw was found on the eve of its original release. And Microsoft actually pulled Windows 10 version 1809 just days after it was released publicly when it finally woke up to the fact—reported multiple times during testing—that it could delete users’ data.

Microsoft was expected to ship the fixed version of Windows 10 version 1809 last Friday, but that date passed without a peep from Redmond. And now we might know why: Users have found a second instance of this release deleting user data. And this one isn’t fixed by the fix.

According to these users, the Compressed Files feature in Windows 10 version 1809 doesn’t prompt the user when you move files or folders out of a ZIP file and those entities already exist in the target location. Instead, it just overwrites the originals.


As with the original data loss bug in this release, this problem had been reported months ago through the ineffectual Windows Insider program, whose purpose now seems unclear. As I’ve observed many times throughout Windows 10’s lifetime, Microsoft collects a lot of data during the development of each version, but it seems to have no understanding of what to do with that data.

Will this bug trigger another delay? Maybe. But it’s equally likely that Windows 10 version 1809 will come (re)racing down the track today, given that it’s a Tuesday. And that Microsoft will fix this issue with yet another quality update, which could be released at any time.

The bigger question is whether Microsoft will ever fix its quality problems. What’s satisfying to me, at least, is that I’m no longer the only one publicly complaining about these problems. I’m not sure what took so long, but welcome to my world, everyone. There are problems here and they need to be discussed and then fixed.
