The Windows key, for Windows Vista (center), the circle around the logo appeared with Windows Vista and 7. The Windows logo key (also known as Windows key, start key, logo key, flag key, super key, command key, flag or home) is a keyboard key which was originally introduced on the Microsoft Natural keyboard in 1994. This key became a standard key on PC keyboards.
In laptop and other compact keyboards it is common to have just one Windows key (usually on the left). Also, on Microsoft's Entertainment Desktop sets (designed for Windows Vista), the Windows key is in the middle of the keyboard, below all other keys (where the user's thumbs rest).
