windows 上的shell是什么样的 具有什么特点,怎样构成的

The shell provides the user with an interface to the objects necessary for running applications and managing the Microsoft® Windows® CE operating system on a target device。 These can be real objects on the target device, such as files and folders; virtual objects, such as the Recycle Bin; or remote objects accessed through a network。
Windows CE allows you to implement a wide variety of shells from simple command line interfaces to fully customized graphical user interfaces adapted for your target device。 A Windows CE shell consists of modules and components that each provide a specific area of shell functionality。
