The Windows logo is a symbol representing the Microsoft Windows operating system. It features four colored squares arranged in a grid, typically displayed in blue, green, yellow, and red. This logo has evolved over the years, reflecting changes in design trends and the overall branding of Windows. Originally introduced in 1985, the logo has undergone several redesigns to align with the visual identity of different Windows versions. The current version, used since Windows 10, emphasizes a clean and modern aesthetic, symbolizing the user-friendly interface and functionality of the operating system.
