In the name "Windows CE," the letters "CE" are not an
abbreviation for anything, but rather they imply a number
of the precepts around which Windows CE is designed,
including "Compact," Connectable,"
Compatible," "Companion," and "Efficient."
Windows CE (also known officially as Windows Embedded
Compact post version 6.0 [2][3], and sometimes abbreviated
WinCE) is Microsoft's operating system for minimalistic
computers and embedded systems. Windows CE is a distinctly
different operating system and kernel, rather than a
trimmed-down version of desktop Windows. It is not to be
confused with Windows XP Embedded which is NT-based
