Many are unaware that many problems within the PC are resolvable with just the keyboard on their computers. Your keyboard is designed to be powerful enough to make changes within the computer without actually going to the Settings or manipulating the configurations or troubleshooting. Windows created commands on the keyboard that allows users to make changes with just a few presses easily. This is so the changing of the settings is more convenient and quick for users. This is often the reason why most settings are made when users accidentally hit random keys.
