What caused the Data Loss problem in Windows 10 v1809
Windows 10 v1809 October 2018 Update was hit by the worst bug till now. A whole lot of end users who upgraded to it described a reduction of files from their user folder. It turned out to be a bug in Windows 10 Upgrade deleted those people files simply because of what is Microsoft calling Known Folder Redirection (KFR) redirection problem. Microsoft is now rolling out a set model with ISO and Media Creation offerings, when those people who have previously up to date to v1809 are obtaining a Cumulative Update 17763.55 (KB4464330) as aspect of the fix. Now let us deep dive into what brought on the knowledge reduction dilemma for those people who installed Windows 10 v1809.
What brought on the Facts Decline in Windows 10 v1809
Known Folder Redirection is a procedure which enables one particular to change the default locale of folders like Downloads, Music, Paperwork, OneDrive, etcetera. to somewhere else on the Laptop with out switching where they show up on the Windows Explorer.
When v1809 was under screening, a couple of end users described that when this procedure was used, they experienced an excess copy of empty folder at those people default locale. Microsoft extra a new established of code in the October 2018 Update to get rid of these empty, replicate recognised folders. This changed put together with one more change to the update sequence, resulted in the deletion of the primary “old” folder locations and their content material, leaving only the new “active” folder intact.
What is even astonishing to take note is that this was a distant problem which was described by a established of end users when this model was with Insiders. Given that Suggestions Hub is based out of voting, this significant problem was buried as it did not get lots of votes from all the end users. Shared by @WithinRafael on Twitter, it is quite crystal clear that Microsoft experienced it missed. IMO any problems which are all-around file deletion have to be taken severely.
Windows Group adds further that the user files were deleted in the subsequent predicaments:
- If the contents of c:usersusernamedocuments were not moved to D:paperwork when the locale was currently being changed, then a user could also experience this problem.
- When the user selected to redirect their folders to one more folder on OneDrive but selected not to shift current files to new locale. Given that those people files were not moved, October Update taken care of them as replicate folders and deleted them.
- If Known Folder redirection was used using an early model of the OneDrive consumer with configurations to flip on the Autosave attribute. The consumer did not shift the aged files to the new locale.
So if the files were still left in the aged locale they where taken off by the Update. Now here is what I am shocked at. Why did end users opt for to leave the files soon after migration to a new locale? Secondly, why were they on the lookout at these folders when they experienced previously migrated to a new locale?
On a connected take note – reviews like these need to trigger worry to Microsoft:
The Gain 10 updates are unpredictable. I’m fearful to death every single time the automatic updates (which I can not disable) come about. After an update one particular of additional installed program halt operating and have to have re-setting up. I have no viruses or cracked program. The very last Gain 10 update corrupted the MBR (Grasp Boot Record) on my two laptops and 1 desktop. 3 pcs accomplished the same update at the same time and possessing corrupted MBRs is NOT a coincidence. Microsoft owes $900 just for this hurt by itself. i spent $300 for every single computer system to have the drives taken off and put new drives in so I can retain my knowledge that was not corrupted in the aged challenging drives. The “reset Gain 10” with out losing own knowledge function in the highly developed configurations was not operating on all 3 pcs. Thank God I experienced 3 spare SSDs as a backup, but it is such a trouble likely through the aged challenging drives and conserving all the knowledge in distinct locations. I’m switching to MAC and ditching everything Laptop connected – Time period!
If you shed your knowledge files, you can test and get well those people files.
Windows 10 v1809 October 2018 Update is now out there for download once more. If you desire to nevertheless perform protected, you may perhaps defer the set up of this attribute update.
