Windows 10 forcefully updated and deleted some of my files

Well, I was working on something on Paint when my laptop suddenly forced an update on me, and now not only can I find what I was doing on paint, I can't find ANYTHING that I downloaded since I upgraded to Windows 10! I didn't even get the option to keep any of my files, and now I have to start from scratch because of something that I had absolutely no control over!
And before you say it, yes I checked Windows.old, and no, nothing was in there.
