Windows 10 1809 update deleted all files from Documents!

After the Geek Squad trying to help, I took my laptop into the nearest MS retail store.  Yesterday they got my permission to send my drive off to their lab for deep work to try and recover anything. Although the store at first did not know what to do (claiming corporate did not advise them) they jumped to help me and got all this going before Level 3 ever called (Oct 13) me back. I dread trying to recreate my financial info. Will post any updates I get.

Bro, the most compensation you're going to get from Microsoft is "we apologize for the inconvenience ..."

There's no doubt that Microsoft scr*wed up v.1809. That's especially true once you understand what went wrong. It was completely avoidable. That said, there are things you could have done to prevent the damage, and while they may not meet the legal definition of 'contributory negligence' you owe yourself a small kick in the pants. Just a small one ... for not paying enough attention.

Microsoft actually doesn't have a utility that backs up all your files at the same time. To do that, you need a third-party backup program. Let's go over what Windows 10 has - and what it really is:

Backup and Restore (Windows 7)  - was included in Windows 10 so that people who used that utility in Windows 7 to make a backup can restore their backup in Windows 10. It's not supported for making new backups. Microsoft should have made that clearer. There's no guarantee that it will work properly to make a backup, and when it doesn't work there's no official solution.

File History - was designed to backup individual files at regular intervals over time. It wasn't built to compete with a real backup program, that backs up all your files at once and has many more features than File History. File History is for "oops ... I liked the old version of my speech better."

System Image Builder - was an image backup program that Microsoft abandoned with the Fall Creators Update. They didn't say exactly why, so here's my guess: There's so much excellent image backup software available from organizations that specialize in this technology, that Microsoft said "why re-create the wheel?"

So if you wanted backup - real backup that you can count on - you needed a real backup program. Like you, I learned this lesson the hard way. (It seems I learn everything the hard way.) But here's what I learned:

There is nothing obvious or intuitive about a computer.

In context: If something has 'backup' in its name, that doesn't mean you can rely on it to do everything you think a backup program should do. You need to find out exactly what it means and what it does. Another example: Anyone who thinks that System Restore will actually restore their system has a big surprise coming.

And once you have your backup program - or any other program - up and running, you have to check it from time to time to see if it's still doing what you expected it to do. Because software changes behind your back, and that's true of anybody's software.

When it comes to backup, the whole idea is to store your backups some place that's not on your computer, so if when something terrible happens to your computer, you still have your backup.

I think you'll just have to wait.

I have tried many non-remedies

It looks like you have the version/build for that update, perhaps you need to wait for it to be offered via windows update.

You could download it again to be sure it's not corrupted and be sure you have the download that corresponds with your build.
