Ok, I may be new but I have been seeing stackloads of posts and threads about force enabling aero. Well the problem with that is that you need to have the minimum requirments, or at least close to them, other than that, there's no way you can force enable aero. The registry hack may work but thats a 10% chance depending on your specifications and system.
Just needed to point that out to people who are getting puzzled. I actually do thing the GFX requirments could have been shortened, cause it worked when I had vista but not with Windows 7.
