Windows 10 1809 update deleted all files from Documents!

Yh i understand think im just in panic mode a little bit as some of that data is irreplaceable, i'll update with file locations,

I dont see how the link is relevant, my files were in a windows.old folder, the microsoft tech support guy told me this is a temp folder, which sounds dubious to me, but regardless the entire directory has been gutted running recovery software now that looks like it may be doing the job

Your link talks about hidden admin accounts and corrupt user accounts neither apply to me, im physically missing 500gb of data from my machine 

A quick scan has found 260gb its currently doing a deep scan so fingers crossed it finds the rest, but this just shouldnt be happening, why would a windows update be deleting data, i work at a software company and if we did anything similar we would be all out of work in a heart beat

Martipello, I have combined all 3 of your replies above.

My point in making the post is not that it will apply to everyone, but there could be some who will benefit, because the underlying reason for the lost files does seem to vary. It will be interesting and potentially helpful to others if you could post the location of the files after your deep scan is finished. That could be a real benefit to many. I would also note that people who are searching for the missing folders/files and hidden identities could benefit by changing their File Explorer settings to "Show Hidden Files" and remove the check mark from "Hide protected operating system files" at least temporarily. 

You are right that this should not happen and that Microsoft is not giving the support that we have a right to expect, but we can't do much about that. All we can do is try to help those affected by posting solutions that could work for at least some of them. I hope that your deep scan does the full job for you.
