7-tan, is the anthropomorphic representation of the Microsoft Windows 7 operating system. She is also known by her development code names, Blackcomb and Vienna, and was portrayed up until recent times as a sleeping android of sorts. However, and like Vista, there has been a surge in diversity of designs, done by both the Japanese and international communities.
