The PowerOpt Rainmeter skin has the most minimalistic theme for the ones who are irritated by the power options in the newer versions of the windows. You will never get to press some hot keys or anything to open up the start button when you have PowerOpt Rainmeter skin. The rainmeter suite offers you one silver power button which pops up into 4. You can choose one according to the action you want to perform - sleep, hibernate, sign out, and shut down. With all these things, the skin also helps you with the time and battery levels.
