Windows Management Instrumentation (WMI)
The Windows Management Instrumentation is basically sets of rules for accessing information about a
notebook. WMI allows an application to determine, for example, the operating system being used,
which hardware and software components are in the notebook, and possibly whether any of the
components need replacing. A local or remote application can use the WMI interface to check which
hardware and software components are installed on your notebook, and might be able to tell how well
they are working or if they need replacement.
Installing the WMI Package
The WMI package is either preinstalled on the notebook’s hard disk or can be downloaded from
http://www.hp.com/toptools (the contents are the same in both cases). The package must be properly
installed before it can be used.
To install the WMI preloaded on the hard disk:
1. Start Windows, if it is not already running.
2. Click Start, Programs (or All Programs), Hewlett-Packard, HP Toptools Agent, Setup.
Using WMI
For a complete description of how to use WMI, see the following documentation provided with the
notebook:
• A README.TXT file: click Start, Programs, Hewlett-Packard, HP Toptools Agent, Read me.
• A Windows online help file describing Hewlett-Packard’s implementation of WMI (group and
attribute definitions): click Start, Programs Hewlett-Packard, HP Toptools Agent, HP Toptools
Help.
Uninstalling the WMI Package
1. Click Start, Programs (or All Programs), Hewlett-Packard, HP Toptools Agent, Uninstall WMI.
2. Restart the notebook.
