Description
The Set-WmiInstance cmdlet creates or updates an instance of an existing Windows Management
Instrumentation (WMI) class. The created or updated instance is written to the WMI repository.
New CIM cmdlets, introduced Windows PowerShell 3.0, perform the same tasks as the WMI cmdlets. The
CIM cmdlets comply with WS-Management (WSMan) standards and with the Common Information Model (CIM)
standard. this enables cmdlets to use the same techniques to manage Windows-based computers and
those running other operating systems. Instead of using Set-WmiInstance, consider using the
Set-CimInstance or
New-CimInstance cmdlets.

This command sets the WMI logging level to 2. The command passes the property to be set and the
value, together considered a value pair, in the argument parameter. The parameter takes a hash table
that's defined by the @{property = value} construction. The class information that's returned
reflects the new value.
Example 2: Create an environment variable and its value
$setWmiInstanceSplat = @{
Class = 'Win32_Environment'
Arguments = @{
Name="testvar"
VariableValue="testvalue"
UserName="<SYSTEM>"
}
}
Set-WmiInstance @setWmiInstanceSplat
__GENUS : 2
__CLASS : Win32_Environment
__SUPERCLASS : CIM_SystemResource
__DYNASTY : CIM_ManagedSystemElement
__RELPATH : Win32_Environment.Name="testvar",UserName="<SYSTEM>"
__PROPERTY_COUNT : 8
__DERIVATION : {CIM_SystemResource, CIM_LogicalElement, CIM_ManagedSystemElement}
__SERVER : SYSTEM01
__NAMESPACE : root\cimv2
__PATH : \\SYSTEM01\root\cimv2:Win32_Environment.Name="testvar",UserName="<SYSTEM>"
Caption : <SYSTEM>\testvar
Description : <SYSTEM>\testvar
InstallDate :
Name : testvar
Status : OK
SystemVariable : True
UserName : <SYSTEM>
VariableValue : testvalue
This command creates the testvar environment variable that has the value testvalue. It does this
by creating a new instance of the Win32_Environment WMI class. This operation requires
appropriate credentials and that you may have to restart Windows PowerShell to see the new
environment variable.
Example 3: Set WMI logging level for several remote computers
$setWmiInstanceSplat = @{
Class = 'Win32_WMISetting'
Arguments = @{LoggingLevel = 2}
ComputerName = 'system01', 'system02', 'system03'
}

...
This command sets the WMI logging level to 2. The command passes the property to be set and the
value, together considered a value pair, in the argument parameter. The parameter takes a hash table
that's defined by the @{property = value} construction. The returned class information reflects
the new value.
Parameters
-Arguments
Specifies the name of the property to be changed and the new value for that property. The name and value must be a name-value pair. The name-value pair is passed on the command line as a hash table. For example:
@{Setting1=1; Setting2=5; Setting3="test"}
Parameter properties
| Type: | Hashtable |
| Default value: | None |
| Supports wildcards: | False |
| DontShow: | False |
| Aliases: | Args, Property |
Parameter sets
-AsJob
Indicates that this cmdlet runs as a background job. Use this parameter to run commands that take a long time to finish.
When you specify the AsJob parameter, the command returns an object that represents the
background job and then displays the command prompt. You can continue to work in the session while
the job finishes. If is used for a remote computer, the job is created on the local computer, and
the results from remote computers are automatically returned to the local computer. To manage the
job, use the cmdlets that contain the Job noun (the Job cmdlets). To get the job results,
use the Receive-Job cmdlet.
To use this parameter together with remote computers, the local and remote computers must be configured for remoting. Additionally, you must start Windows PowerShell using the Run as administrator option. For more information, see about_Remote_Requirements.
For more information about Windows PowerShell background jobs, see about_Jobs and about_Remote_Jobs.
