Nanami Madobe

Technical Details
Windows 7 is an operating system first released on July 22nd, 2009, and to the general public on October 22nd, 2009. It built off of many of the same features introduced in Windows Vista, upgrading them and improving them to be more stable. Windows 7 also introduced multi-touch support, an updated shell, and the HomeGroup networking system. Windows 7, unlike XP and Vista, did not feature many Microsoft programs (such as Movie Maker and Photo Gallery) standard, but instead as part of a free download named Windows Essentials.

Nanami Madobe
Nanami Madobe is the unofficial mascot representing the Windows 7 operating system made by Microsoft. Although it was largely believed that Nanami was official, it was revealed later on that she was designed by artist Wakaba and made by Windows 7 Mania (owned by Techno Alliance Corp). However, her creation led to the first official Microsoft OS-tans, Hikaru Aizawa and the Bing girls. Nanami was a part of a theme complete with images and audio voiced by singer and voice actress, Mizuki Nana, and was released with the first 7777 copies of Windows 7 Ultimate in Japan.

Nanami is depicted as a 15 or so year old girl, with a blue bob cut similar to Windows 2000's and Windows 98's, a schoolgirl-like outfit with the front of the vest shaped into a "7", a rainbow broach in the middle of a bow (possibly being a blended representation of the Windows Logo) and a hairband with a 4-leafed clover shaped pin on it in the colours of the Windows logo. Possibly referencing her increased stability and decreased dependence on RAM, she has a smaller chest than her predecessor, Vista.
