2. How does it work

System Tools software is based on WMI, which stands for Windows Management Instrumentation. WMI’s purpose is similar to that of SNMP (Simple Network Management Protocol): to enable the querying and control of management information in an enterprise – but it has a significantly different architecture under the covers.

Compared to SNMP, WMI provides a higher-level representation of systems, in that it supports properties, events and methods on top of classes of objects, along with a more powerful query language than SNMP supports. Of course, this also means it’s a bit more complex to use and has more overhead on the systems. It has been available in Windows since way back in the Windows 95 and Windows NT era.

WMI is the Microsoft implementation of Web-Based Enterprise Management (WBEM), which is an industry initiative for a standard technology for accessing management information in an enterprise environment. WMI uses the Common Information Model (CIM) industry standard. And as happens with so many implementations of standards – it is not at all interoperable with any other version of the standard.
In other words, WMI is an implementation of ‘standards based’ management, which only works on and with Windows.
