Microsoft says it fixed a Windows 10 update bug that deleted folders

Microsoft can recover lost files Windows 10 October 2018 Update - But You Need To Call Them

Microsoft puts Windows 10 update on hold after file deletion reports

As Microsoft's John Cable explains in a post on Microsoft's Windows Blog, the problem was with the "Known Folder Redirection" feature.

Microsoft may be in a pickle right now due to the hiccupy rollout of its latest Windows 10 October 2018 Update, but that's not stopping the company from supporting the previous versions of Windows 10.

An updated version of the Windows 10 October 2018 Update is distributed to Insider Channels.

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. If there are still files in the "Documents" folder then you're not affected by the issue, according to another tweet from Sarkar. "While the reports of actual data loss are few (one one-hundredth of one percent of version 1809 installs), any data loss is serious", the exec wrote.

The Windows 10 October 2018 Update (version 1809) was made available on October 2nd but hadn't yet been pushed through Windows' automatic update system.

The feature is built-in to the Windows operating system. This caused a new issue, though - users with KFR previously enabled found that files still in their default location were deleted, the idea being that only the new "active" redirected folders would remain. This is the feature that lets you move a known folder like C:\Users\Name\Downloads to D:\Downloads, for example.

Monday, Michael's top sustained winds were around 85 miles per hour (140 kph) as it headed north at 12 miles per hour (19 kph). Forecasters said Michael could be near a very unsafe Category 4 by landfall, with further strengthening expected overnibght.

Microsoft has now fixed this problem, and Windows 10's October 2018 Update should stop deleting these "old" folders full of files.

The fixed versions of Windows are getting floated in Microsoft's Windows Insider Program, which is a program for software testers.

As for users that were affected, the firm says that "Microsoft Support is assisting customers and trying to recover data" and that this support can also be offered by the retail support services in-store.

Microsoft's "Windows 10 Update History" page also contains similar advice for affected users.
