I don't know why it happen. Windows update then Windows create a TEMP Users Folders, put all the documents/download/etc location (path) into one of those temps users folder that was just created. Hopefully my clients didn't lose their files, since the Good users folder was still there.

Okay now Microsoft, listen, it's okay to update your OS. It certainly need it. BUT HOW THE FUCK WOULD YOU CREATE A NEW USERS AND CHANGE THE PATH OF PERSONAL FILES! Thumb up! At least those file were not erased...
