Windows 8 Consumer Preview is a pre-release version of Windows 8 that focuses on people and apps and gives you powerful new ways to use social technologies to connect with the people who are important to you. It's Windows reimagined. Windows 8 Consumer Preview is built on the rock-solid foundation of Windows 7 and has the security and reliability features you expect from Windows, but we’ve made it even better. It’s fast, and it’s made to work on a variety of form factors—especially the new generation of touch devices.
Here’s your chance to be one of the first to try it out. We'll be using information from preview users to make the final product even better.
