Appendix B. WMI reference
This appendix supplies a collection of WMI-related reference material to help you when writing PowerShell scripts that use WMI.
There are a number of WMI namespaces that you’ll often use. These are collected in table B.1.
Table B.1. Useful WMI namespaces
| Namespace |
Comments |
|---|---|
| Root\cim2 | Default WMI namespace; contains the majority of the Win32 classes |
| Root\wmi | Contains many hardware-related classes but is mainly undocumented |
| root\MicrosoftDNS | DNS server management |
| root\virtualization | Hyper-V management |
| Root\MSCluster | Cluster |
| Root\MicrosoftNLB | NLB management |
| Root\webadministration | IIS management |
| root\StandardCimv2 | New classes introduced with Windows 8; drives many of the new modules |
| root\Hardware | Hardware-related data |
| root\Microsoft\Windows\dns | PowerShell v3 DNS client configuration and utilities |
| root\Microsoft\Windows\PowerShellv3 | Information on PowerShell modules |
| root\Microsoft\Windows\Storage | Windows storage server management |
| root\Microsoft\Windows\Smb | SMB management |
The list in table B.2 doesn’t include classes from specific providers, such as DNS or IIS. Those namespaces should be investigated directly. All classes are in the root\cimv2 namespace unless stated otherwise.
