How to Extend Hardware Inventory in Configuration Manager
System Center 2012 Configuration Manager hardware inventory reads information about devices by
using Windows Management Instrumentation (WMI). WMI is the Microsoft implementation of webbased Enterprise Management (WBEM), which is an industry standard for accessing management
information in an enterprise environment.
In previous versions of Configuration Manager, you could extend hardware inventory by modifying
the file sms_def.mof on the site server.
..
In System Center 2012 Configuration Manager, you no longer edit the sms_def.mof file as you did in
Configuration Manager 2007. Instead, you can enable and disable WMI classes, and add new classes
to collect by hardware inventory by using client settings. Configuration Manager provides the
following methods to extend hardware inventory:
Enable or disable existing inventory classes – You can enable or disable the default inventory classes
used by Configuration Manager or you can create custom client settings that allow you to collect
different hardware inventory classes from specified collections of clients.
Add a new inventory class – You can add a new inventory class from the WMI namespace of another
device.
Import and export hardware inventory classes – You can import and export Managed Object Format
(MOF) files that contain inventory classes from the Configuration Manager console.
Create NOIDMIF Files – Use NOIDMIF files to collect information about client devices that cannot be
inventoried by Configuration Manager.
Create IDMIF Files – Use IDMIF files to collect information about assets in your organization that are
not associated with a Configuration Manager client, for example, projectors, photocopiers and
network printers.

Win32_Environment class (Windows)
The Win32_Environment WMI class represents an environment or system environment setting on a
Windows computer system. Querying this class returns environment variables found in:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Sessionmanager\Environment
And HKEY_USERS\<user>\Environment
