Prerequisites

Windows Script Host is built into Microsoft Windows 98, 2000, ME and XP. If you are running Windows 95 or NT4, you can download Windows Script Host from the Microsoft Windows Script Technologies Web site at http://msdn.microsoft.com/scripting/. Some information is not returned on non-NT-based systems.

A reference set in Projects / References to the Microsoft WMI Scripting Library.

The Win32_BaseService abstract WMI class represents executable objects that are installed in a registry database maintained by the Service Control Manager. The executable file associated with a service can be started at boot time by a boot program or by the system. It can also be started on-demand by the Service Control Manager. Any service or process that is not owned by a specific user, and that provides an interface to some functionality supported by the computer system, is a descendent (or member) of this class. Example: The dynamic host configuration protocol (DHCP) client service on a Windows NT/Windows 2000 computer system.

This demo and illustration shows only some of the available information from the class. For a complete listing see the Comments section below. Note that some systems may not return information in all class properties.

BAS Module Code

None.
