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.
예제
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.
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.
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.

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.
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.
매개 변수
-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.
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.
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.
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.
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.
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.
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.
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.
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:
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.
This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable,
-InformationAction, -InformationVariable, -OutBuffer, -OutVariable, -PipelineVariable,
-ProgressAction, -Verbose, -WarningAction, and -WarningVariable. For more information, see
about_CommonParameters.
