Description

The New-CimInstance cmdlet creates an instance of a CIM class based on the class definition on either the local computer or a remote computer. By default, the New-CimInstance cmdlet creates an instance on the local computer.

Examples

Example 1: Create an instance of a CIM class

This example creates an instance of a CIM Class named win32_environment in the root/cimv2 namespace on the computer.

New-CimInstance -ClassName Win32_Environment -Property @{Name="testvar";VariableValue="testvalue";UserName="domain\user"}

No client side validation is performed if the class does not exist, the properties are wrong, or if the server rejects the call. If the instance is created successfully, the cmdlet outputs the newly created instance.

Example 2: Create an instance of a CIM class using a class schema

This example retrieves a CIM class object and stores it in a variable named $class. The contents of the variable are then passed to the New-CimInstance cmdlet.

$class = Get-CimClass -ClassName Win32_Environment
New-CimInstance -CimClass $class -Property @{Name="testvar";VariableValue="testvalue";UserName="Contoso\User1"}

Example 3: Create a dynamic instance on the client

This example creates a dynamic instance of a CIM class named Win32_Process on the client computer without getting the instance from the server. The new instance is stored in the variable $a. This dynamic instance can be used to perform operations if the instance with this key exists on the server.

$a = New-CimInstance -ClassName Win32_Process -Property @{Handle=0} -Key Handle -ClientOnly
Get-CimInstance -CimInstance $a
Invoke-CimMethod -CimInstance $a -MethodName GetOwner

ProcessId Name                HandleCount WorkingSetSize VirtualSize
--------- ----                ----------- -------------- -----------
0         System Idle Process 0           8192           8192

Domain         :
ReturnValue    : 2
User           :
PSComputerName :

The Get-CimInstance cmdlet then retrieves a particular single instance. The Invoke-CimMethod cmdlet calls the GetOwner method on the retrieved instance.

Example 4: Create an instance for a CIM class of a specific namespace

This example gets an instance of a CIM class named MSFT_Something in the namespace root/somewhere and stores it in a variable named $class. The variable is passed to the New-CimInstance cmdlet to create a new CIM instance and perform client side validations on the new instance.

$class = Get-CimClass -ClassName MSFT_Something -Namespace root/somewhere
New-CimInstance -CimClass $class -Property @{"Prop1"=1;"Prop2"="value"} -ClientOnly

In this example, using the CimClass parameter instead of the ClassName parameter validates that Prop1 and Prop2 actually exist and that the keys are marked correctly.

You cannot use the ComputerName or CimSession parameter with the ClientOnly parameter.

Parameters

-CimClass

Specifies a CIM class object that represents the type of the instance. Use the Get-CimClass cmdlet to retrieve the class declaration from a computer. Using this parameter results in better client side schema validations.

Type:	CimClass
Position:	0
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-CimSession

Runs the command using the specified CIM session. Enter a variable that contains the CIM session, or a command that creates or gets the CIM session, such as the New-CimSession or Get-CimSession cmdlets. For more information, see about_CimSession.

Type:	CimSession[]
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-ClassName

Specifies the name of the CIM class of which the operation creates an instance. NOTE: You can use tab completion to browse the list of classes, because PowerShell gets a list of classes from the local WMI server to provide a list of class names.

Type:	String
Position:	0
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-ClientOnly

Indicates that the instance is only created in PowerShell without going to the CIM server. You can use this parameter to create an in-memory CIM instance for use in subsequent PowerShell operations.

Type:	SwitchParameter
Aliases:	Local
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-ComputerName

Specifies the name of the computer on which you want to run the CIM operation. You can specify a fully qualified domain name (FQDN), a NetBIOS name, or an IP address.

If you specify this parameter, the cmdlet creates a temporary session to the specified computer using the WSMan protocol.

If you do not specify this parameter, the cmdlet performs the operation on the local computer using Component Object Model (COM).

If multiple operations are being performed on the same computer, connecting using a CIM session gives better performance.

Type:	String[]
Aliases:	CN, ServerName
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:	SwitchParameter
Aliases:	cf
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Key

Specifies the properties that are used as keys. CimSession and ComputerName cannot be used when Key is specified.

Type:	String[]
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-Namespace

Specifies the namespace of the class for the new instance. The default namespace is root/cimv2. You can use tab completion to browse the list of namespaces, because PowerShell gets a list of namespaces from the local WMI server to provide the list of namespaces.

Type:	String
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-OperationTimeoutSec

Specifies the amount of time that the cmdlet waits for a response from the CIM server. By default, the value of this parameter is 0, which means that the cmdlet uses the default timeout value for the server. If the OperationTimeoutSec parameter is set to a value less than the robust connection retry timeout of 3 minutes, network failures that last more than the value of the OperationTimeoutSec parameter are not recoverable, because the operation on the server times out before the client can reconnect.

Type:	UInt32
Aliases:	OT
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Property

Specifies the properties of the CIM instance using a hash table (name-value pairs).

If you specify the CimClass parameter, then the New-CimInstance cmdlet performs a property validation on the client to make sure that the properties specified are consistent with the class declaration on the server. If the CimClass parameter is not specified, then the property validation is done on the server.

Type:	IDictionary
Aliases:	Arguments
Position:	1
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-ResourceUri

Specifies the resource uniform resource identifier (URI) of the resource class or instance. The URI is used to identify a specific type of resource, such as disks or processes, on a computer.

A URI consists of a prefix and a path to a resource. For example:

http://schemas.microsoft.com/wbem/wsman/1/wmi/root/cimv2/Win32_LogicalDisk

http://intel.com/wbem/wscim/1/amt-schema/1/AMT_GeneralSettings

By default, if you do not specify this parameter, the DMTF standard resource URI http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/ is used and the class name is appended to it.

ResourceURI can only be used with CIM sessions created using the WSMan protocol, or when specifying the ComputerName parameter, which creates a CIM session using WSMan. If you specify this parameter without specifying the ComputerName parameter, or if you specify a CIM session created using DCOM protocol, you will get an error, because the DCOM protocol does not support the ResourceURI parameter.

If both the ResourceUri parameter and the Filter parameter are specified, the Filter parameter is ignored.

Type:	Uri
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type:	SwitchParameter
Aliases:	wi
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

Inputs

None

You can't pipe objects to this cmdlet.

Outputs

Object

This cmdlet returns an object that contains the CIM instance information.
