Microsoft is preparing a much simpler Windows 8 setup and installation process for less-advanced users, potentially reducing the number of clicks from 60 to 11. It will also dramatically reduce the amount of time needed to upgrade systems loaded with lots of files and applications. In addition to the simplified setup, a separate (and more complex) process will be available to those who want to dual-boot multiple operating systems, configure partitions, or perform other advanced tasks.
Microsoft describes the new setup process in the latest post of its Building Windows 8 blog, which has been revealing details of the next version of Windows bit by bit. The overarching theme is reducing the amount of stuff users have to do to upgrade a Windows 7 (or XP or Vista) machine to Windows 8, compressing the size of the OS download, and cutting installation time by optimizing file operations.
