windows 10 (October 2018 update) (version 1809) deleted all my files

Every time there's a feature update, there are people who complain that all their files have been erased. But if there was a 'bug' in the update, wouldn't you think that it would affect just about everybody? We all get the same updates, after all.

So how is it that the majority of Windows 10 PC users don't lose any files at all after an update (including me?) Could there be another explanation?

First: Bugs must not affect everybody. 

Second: An explanation could be, that i erased all files by myself. But that was not the case. ;-)

have any of you actually compared before and after hdd space used? if it is still the same size the files are there. nobody claiming lost files has answered that...

Space is greater than before. I don‘t know the exact amount.

Hello Greg, Ziko and others.

Since 10 years ago I`ve adopting the practice of having two or more HARD DRIVES in my PC (in desktop units it can easily be added). Now, together with the SSD drive for current diary use, I've installed four more HD's. It is easy to do incremental backups and keep information at safe place. These HD's, because more unfrequented access because the main access storage will be to SSD, tends to endure for longer lifetime, and then are a safer place to do periodic backup. I do like not storing my personal and crucial data on the cloud...

I actually wonder if this has anything to do with the change to Storage Sense. It's supposed to switch files in One Drive to online only status or something if they haven't been accessed in a while.
