Watch Windows 8.1 Professional trailer
Windows 8 is built on the rock-solid foundation of Windows 7, but it’s been improved on all fronts. You can install Windows 8 on the same hardware that powers Windows Vista and Windows 7, and you’ll love how it works on new devices, too. Windows 8 was designed with Windows 7 apps in mind, because you probably have older apps you need to use.
