The application Windows Vista Activation and OEM Information tool allows you to install an OEM (those much less expensive copies of Windows) Vista on your computer without it actually being an OEM system. The especially helpful aspect is that you can pick any of the manufacturers (16 to choose from!) and the program will automatically fill in the correct OEM product key information.
This is helpful for security experts as it something new to learn from. Perhaps someone can design a better Windows Genuine Advantage tool from all this. Or you could just install Linux and learn all that mess behind.
