Powercfg or powercfg.exe is a command-line utility that is used to manage all Configurable Power system settings. Powercfg is around for many years and it was first introduced in Windows XP SP2 in 2004. Powercfg command allows you to create, edit, and delete power planes without using the control panel. It nearly allows you to manage almost all the aspects of power plans. Mainly it is used to control the hardware-specific configuration that are not configurable through the control panel. You can run powercfg from an elevated command prompt. And you can configure the Power schemes on a per-user basis. You can do many things using powercfg command.
Powercfg command lines use the following syntax.
powercfg /option [arguments] [/?]
