One of some disadvantage from using the OS Windows 8 (Windows 8 Consumer Preview) is still much that is not yet. Microcode. Microcode is a computer hardware technique that interposes a layer of organisation between the CPU hardware and the programmer-visible instruction set architecture of the computer. As such, the microcode is a layer of hardware-level instructions that implement higher-level machine code instructions or internal state machine sequencing in many digital processing elements.
