Does the Windows 7 system consume a large power consumption?

Microsoft, through its advantages in operating system software research, has increased the efficiency of its energy use to an unprecedented level, with the official claim that Windows 7 is more power-saving than Vista and can save 30%. In an effort to reduce the power consumption, researchers also focused on improving the energy management of the processor. Windows measures its usage based on the number of current processors, and ensures that processor utilization is increased only when absolutely necessary. Windows7 has studied this from several aspects. This includes a smart way to manage: the service on this platform will only start if it reaches a "contact point". In this way, it can also reduce the consumption of electricity.
