Microsoft is now releasing another Cumulative Update to Windows 10 Insiders in the Slow and Release Preview rings. Today's update bumps the build number up from 17763.104 to Build 17763.107. It isn't clear when exactly will Microsoft begin the re-release process of Windows 10 October 2018 Update to the public, but looking at the cumulative updates that are getting smaller by the week, it is likely that we will soon see the latest version made available for the public again.

Today's release fixes the zip file data loss issue that was reported after Windows 10 October 2018 Update rollout process was put to a pause. The company had acknowledged last week that dragging files from a zip file could result in data loss in some scenarios.

“There is a known issue in the Windows 10 October Update where the consent prompt “Do you want to replace these files” is missing when copying contents from a .ZIP file.”

Windows 10 October 2018 Update Build 17763.107 (KB4464455) for Insiders in the Slow and Release Preview rings now fixes that issue along with another problem. The two fixes that today's cumulative update brings, include:

  • We fixed the issue where dragging (extracting) files from a .zip file in File Explorer to a write-protected location you don’t get a “Do you want to replace these files” prompt and the copy action fails silently.
  • We fixed an issue causing roaming profiles to not work correctly.

The company said that today's Windows 10 Version 1809 Cumulative Update contains the same fixes as Build 17763.104 plus the above two additional fixes. While we have no word from Microsoft, if no other surprise issue is reported by Windows 10 October 2018 Update users, it is likely that the company would start rolling out Version 1809 to the public as early as next Tuesday.
