Windows 10 v1809 Oct 2018 Update was striking yesteryear the worst põrnikas till now. H5N1 lot of users who upgraded to it reported a loss of files from their user folder. It turned out to endure a põrnikas inward Windows 10 Upgrade deleted those files because of what is Microsoft calling Known Folder Redirection (KFR) redirection issue. Microsoft is straight off rolling out a fixed version amongst ISO together with Media Creation offerings, piece those who receive got already updated to v1809 are getting a Cumulative Update 17763.55 (KB4464330) equally component of the fix. Now let’s deep dive into what caused the information loss occupation for those who installed Windows 10 v1809.
What caused the Data Loss inward Windows 10 v1809
Known Folder Redirection is a technique which allows ane to alter the default location of folders similar Downloads, Music, Documents, OneDrive, etc. to somewhere else on the PC without changing where they appear on the Windows Explorer.
When v1809 was nether testing, a pair of users reported that when this technique was used, they had an extra re-create of empty folder at those default location. Microsoft added a new laid of code in the Oct 2018 Update to take these empty, duplicate known folders. This changed combined amongst some other alter to the update sequence, resulted inward the deletion of the master copy “old” folder locations together with their content, leaving only the novel “active” folder intact.
What is fifty-fifty surprising to regime annotation is that this was a remote number which was reported yesteryear a laid of users piece this version was amongst Insiders. Since Feedback Hub is based out of voting, this major number was buried equally it did non larn many votes from all the users. Shared yesteryear @WithinRafael on Twitter, it’s pretty clear that Microsoft had it overlooked. IMO whatever issues which are around file deletion must endure taken seriously.
Windows Team adds farther that the user files were deleted inward the next situations:
- If the contents of c:\users\username\documents were non moved to D:\documents when the location was beingness changed, together with therefore a user could besides run across this issue.
- When the user chose to redirect their folders to some other folder on OneDrive but chose non to displace existing files to novel location. Since those files were non moved, October Update treated them equally duplicate folders together with deleted them.
- If Known Folder redirection was used using an early on version of the OneDrive customer amongst settings to plow on the Autosave feature. The customer didn’t displace the onetime files to the novel location.
So if the files were left inward the onetime location they where removed yesteryear the Update. Now hither is what I am surprised at. Why did users guide to larn out the files afterwards migration to a novel location? Secondly, why were they looking at these folders when they had already migrated to a novel location?
On a related regime annotation – comments similar these should displace trace of piece of work organisation to Microsoft:
The Win 10 updates are unpredictable. I’m scared to expiry each fourth dimension the automatic updates (which I tin non disable) happen. After an update ane of to a greater extent than installed software destination working together with request re-installing. I receive got no viruses or cracked software. The final Win 10 update corrupted the MBR (Master Boot Record) on my two laptops together with 1 desktop. iii computers done the same update at the same fourth dimension together with having corrupted MBRs is NOT a coincidence. Microsoft owes $900 only for this harm alone. i spent $300 for each figurer to receive got the drives removed together with position novel drives inward therefore I tin conk along my information that was non corrupted inward the onetime difficult drives. The “reset Win 10” without losing personal information business office inward the advanced settings was non working on all iii computers. Thank God I had iii spare SSDs equally a backup, but it is such a hassle going through the onetime difficult drives together with saving all the information inward dissimilar locations. I’m switching to MAC together with ditching everything PC related – PERIOD!
If yous lost your information files, yous tin elbow grease together with recover those files.
Windows 10 v1809 Oct 2018 Update is now available for download again. If yous wishing to however play safe, yous may defer the installation of this characteristic update.
