The Windows logo is a graphical representation of the Microsoft Windows operating system. It is a stylized version of the Windows flag, which is a four-paned window with a blue background and four white lines. The logo has been used since the first version of Windows was released in 1985. The logo has been updated several times over the years, but the basic design has remained the same. The logo is used to represent the Windows operating system and its associated products and services. It is also used to identify Microsoft as the creator of the Windows operating system.
