It appears that the latest windows 10 Update which is due to roll out tomorrow is deleting all the files in your video,picture, and documents. This is a known big and hopefully Microsoft will fix it before it is pushed out.
Recommend everyone to back up in the next 24 hours in case this bug is not fixed.
Any doubts see the video below on how to prevent the update
There was some news one day ago that Microsoft has pulled the update so it shouldn't come with the next auto-update and also according to the piece of news it has been removed from their download page. So hopefully that is fixed before they push it out again 
Micro$oft always find new ways to impress us .... When updates are supposed to fix bugs and fix security holes they create new Ones ...I won't even talk in deep about the multi-monitor handling wich was far better on Win7 ... New tech always comes with a price ...Good Job Billouuuuu ... I miss the old good WinXP now LoL 
One word of wisdom, most updates no matter if software , hardware should be delayed of atleast 24H in case the repository has been hacked or late bugs to fix etc...
Best of Skills & Luck @ Tables,

@oldschollpapa I agree totally 
In fact I have backed up before the update was pushed onto my system last night. And yes it did wipe all my documents, music, videos and downloads along with password etc. They did not fix this bug and I would recommend to back up.
