What is the configuration required to install Win8?

In the initial stage of the Win8 project, Microsoft's goal is that no matter what the user wants to do on the computer, Win8 will tell you "of course.>. In other words, Win8 is comprehensive in all aspects of low consumption, portability and ease of use.
For example, Win8 does not only provide users with a fixed mode, but can seamlessly switch between different modes according to their preferences and needs. To achieve this goal, first make sure Win8 is suitable for most hardware and peripherals.
Grant George said in a blog post that Microsoft recommends running Win8 on a computer that can be certified with the Win7 logo. The recommended configuration for the Win8 Consumer Preview is as follows:
CPU: 1GHz or faster processor
Memory: 1GB RAM (32 bit) or 2GB RAM (64 bit)
Hard disk: 16GB free hard disk space ( 32-bit) or 20GB of available hard disk space (64-bit)
Graphic card: DirectX 9 graphics device with WDDM 1.0 or higher driver
Because Win8 is full screen display in Metro, so run Metro The style application requires a screen resolution of at least 1024x768. If it is lower than this resolution, you will receive an error when launching the Metro style app.
PS: In addition, if your configuration runs smoothly on Windows 7, you can run smoothly on the same hardware that supports Windows 7
