Win32_OperatingSystem - WMI sample in JScript

The foundations for Manageability in Windows 7/2008/Vista/XP/2000 and Millennium Edition/'98 are Windows Management Instrumentation (WMI; formerly WBEM) and WMI extensions for Windows Driver Model (WDM).

ActiveXperts Network Monitor provides the ability to build monitor check routines based on WMI. ActiveXperts has collected more than a hundred WMI samples. You can use these samples as a base for new check routines you can write yourself.

On this site, you can find many WMI samples.



The Win32_OperatingSystem WMI class represents an operating system installed on a Win32 computer system. Any operating system that can be installed on a Win32 system is a descendent (or member) of this class. If the computer has multiple operating systems installed, this class returns only an instance for the currently active operating system.
