OS Idol Win-chan (Japanese: OSアイドルWinちゃん) is an moe character designed by Mine Yoshizaki for TECH Win, a PC magazine published by Enterbrain. However, the editor-in-chief has suspended the serialization for Win-chan. Since then, multiple derivative works of Win-chan had been released, including fanbooks and figures. She was voiced by Yui Horie, a prominent Japanese voice actress.[1]

Since Win-chan didn't have specific detail on what Windows OS she is based on, it could be assumed that she was a catchall personification of all Windows operating systems.


OS Idol Win-chan's earliest appearance in media seems to be from a promotional CD[2] by Enterbrain, which dates back as early as October 1998. This would mean that Win-chan predates Me-tan by almost 5 years.
