Microsoft has started the process of re-releasing Windows 10 October 2018 Update after the initial release was put to a stop due to a data deletion bug. Windows 10 1809 Build 17763.17 (KB4467228) is now available to Windows Insiders in the Slow and Release Preview rings. The company assured that it will take a slow and steady approach, testing the latest build on the Insider community before making it available to the general public.
In a blog post explaining the bug, Microsoft said that only a few users experienced data loss - "one one-hundredth of one percent of version 1809 installs." It added that the company has now fully investigated all reports of data loss and has identified and fixed all known issues in the update, and conducted internal validation. John Cable, Director of Program Management, Windows Servicing and Delivery, writes (emphasis is ours):
Prior to re-releasing the October 2018 Update our engineering investigation determined that a very small number of users lost files during the October 2018 Update. This occurred if Known Folder Redirection (KFR) had been previously enabled, but files remain in the original “old” folder location vs being moved to the new, redirected location. KFR is the process of redirecting the known folders of Windows including Desktop, Documents, Pictures, Screenshots, Videos, Camera Roll, etc. from the default folder location, c:\users\username\<folder name>, to a new folder location. In previous feedback from the Windows 10 April 2018 Update, users with KFR reported an extra, empty copy of Known Folders on their device. Based on feedback from users, we introduced code in the October 2018 Update to remove these empty, duplicate known folders. That change, combined with another change to the update construction sequence, resulted in the deletion of the original “old” folder locations and their content, leaving only the new “active” folder intact.
Microsoft added that all the issues have now been resolved and the rollout process for the public will be resumed after the feedback is received from the Slow and Release Preview rings.
Windows 10 1809 cumulative update (KB4464330) is available to those who have already installed the latest version
Today's Windows 10 1809 cumulative update (build 17763.55) addresses the data deletion issue along with bringing the usual Patch Tuesday security fixes to the OS. Here's the complete changelog:
- Addresses an issue where an incorrect timing calculation may prematurely delete user profiles on devices subject to the "Delete user profiles older than a specified number of day” group policy.
- Security updates to Windows Kernel, Microsoft Graphics Component, Microsoft Scripting Engine, Internet Explorer, Windows Storage and Filesystems, Windows Linux, Windows Wireless Networking, Windows MSXML, the Microsoft JET Database Engine, Windows Peripherals, Microsoft Edge, Windows Media Player, and Internet Explorer.
Microsoft is also making some changes to the Windows Insider Feedback Hub, adding a new feature for users to "provide an indication of impact and severity when filing User Initiated Feedback." Since the data deletion issue was reported ahead of the public release of Windows 10 1809 and attracted quite a backlash from users, the step is being taken to understand the severity of the issues and to "better monitor the most impactful issues even when feedback volume is low."
The Windows maker apologized through today's blog post and has promised to "move towards an official re-release of the Windows 10 October 2018 Update" once there is a confirmation that there are no further issues with the latest version of Windows 10.
