Microsoft squashes data-eating bug in the Windows 10 October 2018 update

Microsoft says that they have analyzed all reports of data loss and conducted an internal investigation to find out the cause of the files removal.

Apart from these, Microsoft has also released Windows 10 cumulative update to version 1703 Build 15063.1387 (KB4462937), and version 1607 Build 14393.2551 (KB4462917), which is only available for Windows 10 Enterprise and Windows 10 Education editions as version 1607 reached the end of service on April 10, 2018.

Cable also identified another file deletion scenario involving redirection of Known Folders to OneDrive storage whereby contents of the original default directory were erased if they weren't moved.

Microsoft's John Cable went into more detail over here. It says that a "very small" number of users lost files, and the data loss occurred if Known Folder Redirection (KFR) was enabled previously, but the files were still in the original folder location rather than having been moved into the redirected location.

Windows 10 October 2018 Update was officially released at Microsoft's Surface hardware event last week and the upgrade promises to deliver a ton of new functionality. This has led to Microsoft lifting the lid on its October Update once again to Windows Insiders, with plans for an official release upon "confirmation that there is no further impact". "This vulnerability has a Base CVSS score of 7 and is present in all operating systems with updates this month from Server 2008 through Windows 10". The company did toss a bone to Enterprise and Education customers recently, basically enabling them to install just one feature update every other year. (I am sure a number of users do this unknowingly by checking for updates once a new feature update rolls out.) Even after the first two or three or four cumulative updates roll out for a new feature update, I am still leery about putting it on my PC.

An updated version of the Windows 10 October 2018 Update is distributed to Insider Channels. To fix that, "we introduced code in the October 2018 Update to remove these empty, duplicate known folders". You create "D:\documents" and change the location of the files known folder from the original "old" location c:\users\username\documents to D:\documents. Hopefully, this will teach Microsoft not to skip its Release Preview testing in the future. Still, if you lost any personal data after proceeding, be aware that Microsoft will offer free customer support online and at its retail stores.
