When I boot into Windows on my Macbook Pro, I am unable to make the external monitor the default monitor.

So when I play games full screen, they automatically open up on my laptop monitor. I want them to open up on my secondary monitor. The only solution I found to this is to make my external monitor mirror my laptop monitor.

I can't even close the lid of the laptop monitor because that will cause the system to go to sleep.

I think I had the same problems once. What kind of gpu is your MBP using? Ati or Nvidia? In case it's Ati, I think there is a website that offers modified catalyst control center version that work in bootcamp. With the modified ccc installed I was able to set my default monitor to the external. Unfortunately I can't provide you with any links because I'm traveling right now.
