|fnote= }} Windows 3.1-tan (3.1たん) is one of the less common Windows personifications. 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 more increasingly common is a frail grey-haired young woman in a long frilly violet gown, with a 3.1 brooch on her collar. She is usually accompanied by either a black cat or a small black-haired catgirl in a nurse's outfit, both representing DOS.
