By default, Windows 10 come with three power plans: High Performance, Balanced, and Power Saver. These plans are designed to quickly let you switch a group of hardware and system power settings (like display, sleep, etc). Your PC can have additional power plans defined by its vendor. These power settings affect how long your battery lasts and how much power your PC consumes. It is possible to customize these power plan settings but it requires too many clicks to get there. If you change these settings often, you can use a special command to directly open them.
Windows 10 comes with a new UI again to change the operating system's power related options. The classic Control Panel is losing its features and probably will be replaced by the Settings app. The Settings app has already got many settings which were exclusively available in the Control Panel. The battery notification area icon in the Windows 10 system tray was also replaced with a new Modern UI. If you want to switch power plans quickly, there is no way yet. So instead, you can add the appropriate options to change the power plan to the desktop context menu. It will provide you the ability to switch the power plan with one click in Windows 10.
