# AvoidUsingWMICmdlet

**Severity Level: Warning**

## Description

As of PowerShell 3.0, the CIM cmdlets should be used over the WMI cmdlets.

The following cmdlets should not be used:

- `Get-WmiObject`
- `Remove-WmiObject`
- `Invoke-WmiMethod`
- `Register-WmiEvent`
- `Set-WmiInstance`

Use the following cmdlets instead:

- `Get-CimInstance`
- `Remove-CimInstance`
- `Invoke-CimMethod`
- `Register-CimIndicationEvent`
- `Set-CimInstance`

The CIM cmdlets comply with WS-Management (WSMan) standards and with the Common Information Model
(CIM) standard, allowing for the management of Windows and non-Windows operating systems.

## How

Change to the equivalent CIM based cmdlet.

- `Get-WmiObject` -> `Get-CimInstance`
- `Remove-WmiObject` -> `Remove-CimInstance`
- `Invoke-WmiMethod` -> `Invoke-CimMethod`
- `Register-WmiEvent` -> `Register-CimIndicationEvent`
- `Set-WmiInstance` -> `Set-CimInstance`

## Example

### Wrong

```powershell
Get-WmiObject -Query 'Select * from Win32_Process where name LIKE "myprocess%"' | Remove-WmiObject
Invoke-WmiMethod -Class Win32_Process -Name 'Create' -ArgumentList @{ CommandLine = 'notepad.exe' }
```

### Correct

```powershell
Get-CimInstance -Query 'Select * from Win32_Process where name LIKE "myprocess%"' | Remove-CIMInstance
Invoke-CimMethod -ClassName Win32_Process -MethodName 'Create' -Arguments @{ CommandLine = 'notepad.exe' }
```
