If you are a geeky computer nerd you have probably already heard about the pre-release version of the next Windows operating system, Windows 7 Beta. Microsoft is allowing IT professionals, developers, small-business owners, and consumers to download the pre-release Windows 7 for use on a dedicated test computer. The customer preview program for Windows 7 Beta will end soon though, so download and activate the operating system as soon as you get a chance, or you may miss out on the testing phase experience.
