My machine is running Windows 7 64 bit. Any idea how to run the game in windowed mode?

Unfortunately most of my findings are for Vista. I'm not sure as to whether or not you've tried them, or if they'll work. Here's a couple, sorry if I couldn't have been more help.

i dont really think theres a way but i know theres a mod tester type thing that lets you play the game windowed but its all like fast and wierd and its not for gameplay its for testing.

What the best posted is correct. Add "/win" to the target of the shortcut and it will run windowed.
