Both variations of the personification of Windows NT are not very common. The first such, NT-tan, usually has the purple hair and the pink dress seen here, but her age can range from child to adult. Sometimes she is also portrayed as the mother of 2K-tan. Another version, Windows NT Workstation, also exists and has recently been more common than the original NT-tan, at least on the Futaba image boards. NT has the romaji representation of enu ti—this sounds a lot like inu ti, and inu is the Japanese word for dog. Inu-T has blue hair, dog ears, a dog's tail and a collar. She usually wears gloves and boots shaped like paws, and colored blue to match her ears and tail. Yet another NT-tan, Windows NT SP6, was designed by the dōjinshi group Deja vu, but it was considered a bootleg design by Futaba society and not an official OS-Tan.
