CE-tan
From OS-Tan Collections Wiki
Being an OS designed for small devices, the personification of Windows CE (CE for short) is portrayed as diminutive and fairy-like; complete with gossamer wings and wielding a USB cable wand. Because a modified version of Windows CE was the operating system of the Sega Dreamcast console, there are several illustrations of CE standing upon or around the Dreamcast's swirl logo.
