The Windows taskbar originated from the Microsoft project "Cairo," launched in 1991, which introduced a design with visible fields at the bottom of the screen. The Windows 95 taskbar combined this design with the window-minimizing functionality from Windows 3.1. Although a similar concept appeared in the 1988 NeXTSTEP operating system, Microsoft veterans assert that the Windows taskbar was developed independently, without inspiration from NeXT. The NeXTSTEP solution later influenced the macOS Dock. The taskbar continues to evolve while maintaining its significance in user interface design.
