Microsoft claims it fixed a bug in Windows 10 that completely deleted files for some users. However, a new update has still not been released.
The tech giant has released a new Windows 10 update for testers after pulling out the October 10, 2018 release.
Despite claims that the latest patch eliminates the deletion issues, additional issues prevent Microsoft from publishing the new update to the public.

Microsoft has fixed a bug in its latest Windows Update of October 10, 2018, which has deleted files for some users in bulk. However, additional issues seem to prevent the new update from being released
WHY WAS USER FILES DELETED IN WINDOWS 10 2018?
Microsoft has detected the cause of an error that has deleted user files.
It was bound to a feature called Known Folder Redirection.
Code introduced with the October 10 Windows Update removed empty and duplicate known folders after users redirected their files.
However, it turned out that in some known folders still files were deleted.
The company has released a patch to keep the known folder and its files "intact".
The software giant had to carry out the update of 10 October 2018 due to data deletion problems.
Microsoft claims it will be shared only with members of the Windows Insider program before it becomes available to the general public.
"We thoroughly investigated all the data loss reports, identified and fixed all the known issues of the update, and conducted an internal review," said John Cable, Director of Program Management for Windows Maintenance and Delivery at Microsoft.
"… We will carefully review the results, feedback and diagnostic information provided by our insiders before taking further steps towards re-publishing."
Mr. Cable said that the mass-erasure error only affected a small number of users – especially those who manually enabled the "Check for Updates" feature before the update was released more extensively.
The update was then taken offline only two days after launch.
Microsoft estimates that the number of users affected was one-hundredth of a percent of installations, but data loss is still considered "serious."
ZDNet estimates, however, that several hundred people could have lost their files.
The company believes that the bug may have been tied to a feature known as folder redirection.

Known folder redirection allows users to redirect folders such as documents, desktop, and pictures from the default location.
Microsoft introduced code in the 2018 update to remove these empty and duplicate known folders. In some cases, however, there was still some data in the folders.
Well, with the reissue of Windows 10 2018, the company says they've added a patch.
"We thoroughly investigated these issues and developed solutions that would solve all three scenarios, so the old location of the original folder and its contents are preserved," said Cable.
The company said it received early user reports about the error, but did not take any action because the total number of reports was too low to be displayed by the engineers.
As a result, there is now a feature that allows users to specify the impact and severity of user-initiated feedback, making engineers more aware of serious issues.
"We expect to be able to better monitor the impact, even with low feedback volumes," said Cable.
