95-tan is a personification of the Microsoft Windows 95 operating system in the OS-tan series, which is a collection of fan-created anthropomorphic characters representing computer operating systems. In the series, 95-tan is typically depicted as a teenage girl with a green dress and a ribbon, often symbolizing the Windows 95 logo's color scheme. She is portrayed as nostalgic and somewhat old-fashioned, reflecting her role as a once-popular but now outdated OS. 95-tan often interacts with other OS-tans, serving as an elder sister figure to newer Windows-tans, and represents the transition from early to modern Windows systems.
