Desktop folder and files disappeared

view story

http://askubuntu.com – I restarted my computer, and when I logged back in, I noticed that all of my files that were on the desktop are gone. Instead, icons of all of my home folder are showed on my desktop. I opened the terminal and found out that there is no ~/Desktop folder. What happened? What do I need to do? 12.04 32-bit WUBI installed. (HowTos)
