<3 the pink one
The second from the left? She’s Yū Madobe, Windows RT’s personification.

From left to right: Ai Madobe (Windows 8.x), Yū Madobe (Windows RT), Tōko Madobe (Windows 10), Nanami Madobe (Windows 7, 1st official Windows OS-tan) and Claudia Madobe (Windows Azure). All of them are official OS-tan, by MS itself.
Can someone add some notes on it?
