WshShell Object

Microsoft® Windows® 2000 Scripting Guide

The shell is the component of Windows that presents users with an interface to the operating system and provides familiar elements of the Windows desktop experience, including Windows Explorer, the Start menu, shortcuts, and desktop themes.

The WshShell object gives your scripts the ability to work with the Windows shell. Your scripts can use the WshShell object to perform a number of system administration tasks, including running programs, reading from and writing to the registry, and creating shortcuts.

Figure 3.10 shows the properties and methods of the WshShell object.
