I've seen tons of articles and a video about this update deleting other users' files, so I made an account on the only forum where I think I can get good advice.

The video is from ThioJoe, I know, but he actually seems to be really serious about this.
I'm still skeptical about this though, but should I go on and update Windows anyway?
I really don't want to lose any data, since I don't have any backups yet.
