It's easy for us to get WMI classes by performing PowerShell cmdlet. We can perform Get-WmiObject -List or Get-CimClass to get WMI classes.
Remark: To use Get-CimClass cmdlet, we need to install Windows Management Framework (WMF) 3.0 or later.
By default, Get-WmiObject -List and Get-CimClass show all WMI classes which are under Root\Cimv2. To get other WMI classes, we need to add -Namespace into Get-WmiObject and Get-CimClass cmdlets. Using Get-CimClass, we can use tab key to find the namespace.
