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.
Use the Property parameter to set the initial values of the selected properties.
By default, the New-CimInstance cmdlet creates an instance on the local computer.
PARAMETERS
-CimClass
Specifies a CIM class object that represents the type of the instance.
You can use the Get-CimClass cmdlet to retrieve the class declaration from a computer.
Using this parameter results in better client side schema validations.
Required? true
Position? 1
Default value none
Accept pipeline input? True (ByValue)
Accept wildcard characters? false
-CimSession
Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such
as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local
computer.
Required? true
Position? named
Default value none
Accept pipeline input? True (ByValue)
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 Windows PowerShell gets a list of
classes from the local WMI server to provide a list of class names.
Required? true
Position? 1
Default value none
Accept pipeline input? True (ByPropertyName)
Accept wildcard characters? false
-ClientOnly []
Indicates that the instance is only created in Windows PowerShellr without going to the CIM server. You can
use this parameter to create an in-memory CIM instance for use in subsequent Windows PowerShell operations.
Required? false
Position? named
Default value none
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
Ws-Man 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.
Required? false
Position? named
Default value none
Accept pipeline input? True (ByPropertyName)
Accept wildcard characters? false
-Key []
Specifies the properties that are used as keys. CimSession and ComputerName cannot be used when Key is
specified.
Required? false
Position? named
Default value none
Accept pipeline input? True (ByPropertyName)
Accept wildcard characters? false
-Namespace []
Specifies the namespace of the class for the new instance.
The default namespace is root/cimv2.
Note: You can use tab completion to browse the list of namespaces, because Windows PowerShell gets a list of
namespaces from the local WMI server to provide the list of namespaces.
Required? false
Position? named
Default value none
Accept pipeline input? True (ByPropertyName)
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.
Required? false
Position? named
Default value none
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.
Required? false
Position? 2
Default value none
Accept pipeline input? True (ByPropertyName)
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.
Required? true
Position? named
Default value none
Accept pipeline input? True (ByPropertyName)
Accept wildcard characters? false
-Confirm []
Prompts you for confirmation before running the cmdlet.Prompts you for confirmation before running the cmdlet.
Required? false
Position? named
Default value false
Accept pipeline input? false
Accept wildcard characters? false
-WhatIf []
Shows what would happen if the cmdlet runs. The cmdlet is not run.Shows what would happen if the cmdlet runs.
The cmdlet is not run.
Required? false
Position? named
Default value false
Accept pipeline input? false
Accept wildcard characters? false
This cmdlet supports the common parameters: Verbose, Debug,
ErrorAction, ErrorVariable, WarningAction, WarningVariable,
OutBuffer, PipelineVariable, and OutVariable. For more information, see
about_CommonParameters (https:/go.microsoft.com/fwlink/?LinkID=113216).
INPUTS
None
This cmdlet accepts no input objects.
OUTPUTS
System.Object
This cmdlet returns an object that contains the CIM instance information.
Example 1: Create an instance of a CIM class
PS C:\>New-CimInstance -ClassName Win32_Environment -Property
@{Name="testvar";VariableValue="testvalue";UserName="domain\user"}
This command creates an instance of a CIM Class named win32_environment in the root/cimv2 namespace on the
computer.
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, then the New-CimInstance cmdlet outputs the newly created instance.
Example 2: Create an instance of a CIM class using a class schema
PS C:\>$class = Get-CimClass -ClassName Win32_Environment
PS C:\> New-CimInstance -CimClass $class -Property
@{Name="testvar";VariableValue="testvalue";UserName="Contoso\User1"}
This set of commands retrieves a CIM class object and stores it in a variable named $class using the Get-CimClass
cmdlet. The contents of the variable are then passed to the New-CimInstance cmdlet.
Example 3: Create a dynamic instance on the client
PS C:\>$a = New-CimInstance -ClassName Win32_Process -Property @{Handle=0} -Key Handle -ClientOnly
PS C:\> Get-CimInstance -CimInstance $a
PS C:\> Invoke-CimMethod -CimInstance $a -MethodName GetOwner
This set of commands creates a dynamic instance of a CIM class named win32_Process on the client computer without
getting the instance from the server. This set of commands retrieves the dynamic instance and stores it in a
variable named $a and passes the contents of the variable to the Get-CimInstance cmdlet. The Get-CimInstance
cmdlet then retrieves a particular single instance, and invokes the GetOwner method using the Invoke-CimMethod
cmdlet.
This dynamic instance can be used to perform operations if the instance with this key exists on the server.
Example 4: Create an instance for a CIM class of a specific namespace
PS C:\>$class = Get-CimClass -ClassName MSFT_Something -Namespace root/somewhere
PS C:\> New-CimInstance -CimClass $class -Property @{"Prop1"=1;"Prop2"="value"} -ClientOnly
This set of commands gets an instance of a CIM class named MSFT_Something in the namespace root/somewhere and
stores it in a variable named $class using the Get-CimClass cmdlet. The contents of the variable are then passed
to the New-CimInstance cmdlet to create a new CIM instance and perform client side validations on the new instance.
If you want to validate the instance, for example, to make sure Prop1 and Prop2 actually exist and that the keys
are marked correctly use the CimClass parameter instead of the ClassName parameter.
You cannot use the ComputerName or CimSession parameter with the ClientOnly parameter.
