Windows CE <operating system> /C E/ A version of the {Microsoft Windows} {operating system} that is being used in a variety of {embedded} products, from {handheld} PCs to specialised industrial {controllers} and consumer electronic devices. Programming for Windows CE is similar to programming for other {Win32} {platforms}. Windows CE was developed to be a customisable operating system for embedded {applications}. Its {kernel} borrows much from other Microsoft {32-bit} operating systems, while eliminating (or replacing) those operating system features that are not needed for typical Windows CE-based applications. For example, as on {Windows NT}, all applications running on Windows CE run in a fully {preemptive multitasking} environment, in fully {protected memory} spaces. The {Win32} (API) for Windows CE is smaller than the Win32 API for the other 32-bit Windows operating systems. It includes approximately half the interface methods of the Windows NT version of the API. But the Win32 API for Windows CE also includes features found in no other Microsoft operating system. The notification API, for example, makes it possible to handle user or application notification events (such as timer events) at the operating-system level, rather than in a running application. The {touch screen} API and the built-in support for the Windows CE {database} are not found in other Windows operating systems. The touch screen API makes it easy to manage screen calibration and user interactions for {touch-sensitive displays}, while the database API provides access to a data storage facility.
