Summary
CIM is an open-source standard for accessing and displaying information about a computer, while WMI is Microsoft's implementation of CIM for the Windows platform. CIM includes some standard classes that represent information like computer hardware and software, and can be extended by vendors to add properties relevant to their products. PowerShell provides two management interfaces for accessing data on a computer: WMI and CIM. CIM is the better option for accessing data on a remote computer due to its more secure protocol and more control over the data transfer. The biggest advantage of using CIM instead of WMI is that CIM is designed to work in heterogeneous environments, while WMI works really well for managing Windows machines.
