The “Madobe Family” (窓辺家, Madobe-ka) refers to a line of unofficial Microsoft-related gijinkas designed by a Japanese DSP¹⁾ distributor named “Windows Navi+” (Techno-Alliance Corp.). While similar in concept, the family is actually separate from the original OS-tans.

To keep the character sections less clustered, I've moved the birth dates, voice actress, and Twitter handles to the following chart below:

Nanami Madobe (窓辺ななみ) is the Windows 7 girl who had short blue hair, a white headband, a Windows clover head accessory, a blue-white outfit, a plaid skirt with a Windows-like trim, and knee socks. She likes bread, sakura anpan, milk at school, barley tea in the summer, and window shopping. It's also known that she's in the water polo club, washes her hair first, has good eyesight, but has modest boobs.

Yuu Madobe (窓辺ゆう) and Ai Madobe (窓辺あい) are twin sisters who represent Windows 8.²⁾ Yuu is the older sister with short brown hair and twin ponytails that loves digital gadgets, seeing Akihabara, and has three computers. Ai is the younger sister with long brown hair and a side ponytail that loves new things, social media, surfing the web, and homebuilt computers.

Claudia Madobe (クラウディア窓辺) is the Microsoft Azure girl with short blonde hair, red glasses, a beige cardigan with a white undershirt, and a blue skirt. She originally debut in Cloud Girl (クラウドガール). This isn't explicitly mentioned, but her mother is French-American and she also has a fully-designed brother by the name of Claude Madobe (クロード窓辺), though I presume that a majority of you aren't here for that.

Touko Madobe (窓辺とおこ), also romanized as Tōko Madobe, is the Windows 10 girl with white hair, a blue-white outfit, a Metro-colored tie, and a blue-white skirt with a 10 next to a strip of Metro colors resembling the desktop. She was originally introduced as a 17-year-old time traveler from 100 years into the future, thus her placement on the family tree was supposed to be vague.
