Windows 3.1
Windows 3.1-tan (3.1たん) was one of the less common Windows personifications but is now part of the OS-tan canon. The first appearances of Windows 3.1 have used a white mech-box similar to that used by 98 and 98SE, piloted by a girl who appears to be DOS/V. Another version that has became increasingly common and became part of the OS-tan canon is that of a frail grey-haired young girl in a long frilly violet gown, with a 3.1 brooch on her collar. She has a quiet personality and is usually accompanied by either a black cat (sometimes nicknamed DOS Kitty) or a small black-haired catgirl in a nurse's outfit, both representing DOS. She is often seen with Windows NT-tan and 95-tan but has an inseparable relationship with DOS Kitty as Windows 3.x is highly dependent on DOS especially compared to its successors which mainly used a stripped-down version of DOS for booting.
