you formatted your harddrive for nothing!
All you had to do was hit CTRL-SHIFT-ESC, go to file, then "New Task (run)" then browse to your "windows folder" and open up "explorer.exe". There is another way but i have forgotten where it is located in the registry. This way is a gr8 prank as well to play on your friends. You can use it to, turn their computer into a word processor! lol PM me for more information.
