Hardware Profiles on Win7

While I was on vacation I was in the IRC and there was a person there whom knew how to set these up in Windows. It was a new feature of Win7, or just easier to do, that required a tweak here and there that you could specify what the default GPU was on a per application basis. What this would allow to happen is for those of us with multiple graphics cards, we could now use them for different instances of WoW with out the pain of swapping primary displays, starting some, and swapping back to start the rest.

Well I have been back from vacation and would Love to look into this again as this would allow me to use up to 4 monitors (Main wow, 2 wow, 2 wow and Everything else). is anyone in the know on this? Is the guy from IRC still lurking around the forums? (Ive not see anyone in the channel)

Anywho, google searches will continue but I figured the post might help as well :)
