My computer (ACER) has windows 10. Mid-last week, overnight, the windows updated by itself. The entire format of my computer change and my documents were all moved around. I generally keep most of my documents on the desktop, which was now moved into another separate folder that I had to find. I found that folder and moved all the files back into my desktop. Overnight, the update "reversed" itself somehow, and the version was back to what it was the previous day when the update had not happened. Now, all my documents were deleted, as they were no longer showing in my desktop. I assume that because I moved them from whatever folder the initial update had kept them in, this got screwed over. I could not find the files anymore, and I suddenly had over 150gb of free space. I used recuva to recover some files, but many are now not reoverable/usable/openable. What just happened? It's extremely frustrating, as the auto update and auto "reverse" update just did that by itself.
