The Windows key is a special key found on most keyboards designed for use with the Windows operating system. It typically features the Windows logo and is located between the Ctrl and Alt keys on the left side of the keyboard. Pressing this key opens the Start menu, allowing users to access applications, settings, and files quickly. In addition to opening the Start menu, the Windows key can be used in combination with other keys to perform various shortcuts. For example, pressing the Windows key + D minimizes all open windows, while Windows key + L locks the computer. These shortcuts enhance productivity and streamline navigation within the Windows environment.
