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
