my brother has a computer and he keeps a lot of his important files on his desktop. yes we are aware that in hindsight that was a poor decision. one day he woke up and went on his computer and a ton of his files on the desktop were gone for no reason. we cant figure out why. i have asked him if he downloaded anything sketchy and he said no. we tried restoring the files using restore points but there werent any restore points to load, even though my brother has stated he created one in the past. we checked file history and it said it was turned off and we couldnt turn it on. the button that said "turn on" was grayed out. thats all we can think to try. how and why could this have happened, and more importantly can we get the files back somehow? any input welcome. thanks.
