Microsoft patches file-deletion glitch in Windows 10 October update

Microsoft has released a fix for a bug found in the Windows 10 October Update that led to users to inadvertently overwriting files when moving them from compressed folders.

Redmond yesterday released a cumulative update to the maligned version 1809, currently just available for Windows Insiders, that fixed the compressed files bug, as well as a separate issue that caused roaming profiles to not work correctly.

The bug affected the built-in ZIP tool in Windows File Explorer when users moved files from a compressed folder, to another folder containing files with the same name.

A dialogue box asking users whether they wish to replace an identical file, skip, or compare information failed to show, and skipped these files by default.

Because files would 'skip', cutting-and-pasting them meant users would have inadvertently deleted the files they had wished to move across. Users who copy-and-pasted compressed files could have been given the impression their files were seamlessly copied over, before subsequently deleting the compressed folder.

The fix, released with Build 17763.107 (KB4464455), was promised for "early November" when Microsoft first acknowledged the prevalence of this issue last week. Microsoft had initially warned users with version 1809 not to cut and paste items from compressed folders.

This has been released following a previous update to the current Windows 10 iteration, version 1803, which fixed up to 40 separate bugs including a handful of Bluetooth errors and glitches that enterprise admins had complained update.

Update 1809 meanwhile has been ridden with several errors since Microsoft first began rolling it out at the beginning of October, including a high-profile file-deletion error.

This led to Microsoft pulling the October Update entirely in order to correct the issues, before undergoing a second roll-out to Windows Insiders.

The major update is still only available to Windows Insiders, who continue testing the operating system for any further bugs, and there is no concrete word as to when it will again be made generally available.
