Getting Started with WMI Scripting

Operating System:
As the name implies, you'll need Windows (Windows 95 or later).
WMI is not limited to a single language or interpreter, but can be used in many languages: (XP) batch files, Perl, KiXtart, WSH (JScript/VBScript), Object Rexx, PowerShell, Python, C#, Visual Basic, ...
There is a language for WMI queries, not surprisingly called WMI Query Language or WQL, which is a subset of SQL.
Client software:
The WMI client software is installed by default in Windows ME/2000 and later versions.
For Windows 95/98/NT 4 download and install the WMI core 1.5.
Development software:
Several query and code generators are available for several scripting languages.
The most well-known is without a doubt the Scriptomatic tool, which is a really great learning as well as "production" tool.
I also recommend working with Windows own WBEMTEST, which is part of the WMI client software.
Help files:
Download the WMI Tutorial.
And use Microsoft's online WMI Reference, especially when you intend to use your WMI queries on different Windows versions.
Study WQL (WMI Query Language, or SQL for WMI).
I compiled a short list of books on WMI.
Start by examining sample WMI scripts and exploring other WMI related sites.
