Using the optimizing compiler in Visual Studio? (Score 2, Interesting)

Has anyone managed to apply this download to a Visual Studio .NET 2003 Standard installation, to get the benefits of an optimizing compiler?

Standard edition disables the optimizing compiler. You have to pay for Professional edition to get the optimizer. Being cheap, and not needing all the .NET crap in Professional addition, I bought Standard edition. Now it seems MS is giving away the optimizing compiler. But how to enable its use from within Visual Studio? has anyone figured out a way to do this?
