Warcraft 3 Frozen Throne does infact work on the developer preview.

However, it does require some steps to make it work.

You have to make a shortcut onto your desktop and run it in compatibility mode for windows XP service pack 3. The game does work, but there is no sound.

I don't need to run the Warcraft III in compatibility mode, but the sound is still now working.
Can you make Warcraft III's sound to work?
