The document provides an introduction to Windows Management Instrumentation (WMI) and how to use it with Perl. WMI is a set of standards created by DMTF to manage Windows systems. It consists of DMI, WBEM and CIM. The document discusses how WMI works, connecting to it from Perl using monikers or SWBEM Locator, executing WQL queries, and provides examples of practical uses like getting route information, adding/deleting routes, and refreshing performance counter data. Practical code samples are provided in both VBScript and Perl scripting language (PLS).

quot;Scriptomaticquot;
• quot;A completely new version of the famous Scriptomatic, the utility that
writes WMI scripts for you.
(And, in the process, teaches you the fundamental concepts behind
writing WMI scripts for yourself.)
• Unlike its predecessor, Scriptomatic 2.0 isn’t limited to writing just
VBScript scripts; instead, Scriptomatic 2.0 can write scripts in Perl,
Python, or JScript as well.
• In addition, Scriptomatic 2.0 gives you a host of new output formats to
use when running scripts, including saving data as plain-text, as a
stand-alone Web page, or even as XML. Scriptomatic 2.0 handles arrays,
it converts dates to a more readable format, and it works with all the
WMI classes on your computer; on top of all that, it also writes scripts
that can be run against multiple machines.“*
