The Set-ItemProperty cmdlet changes the value of the property of the specified item. You can use the cmdlet to establish or change the properties of items. For example, you can use Set-ItemProperty to set the value of the IsReadOnly property of a file object to $True.

You also use Set-ItemProperty to create and change registry values and data. For example, you can add a new registry entry to a key and establish or change its value.

This command sets the value of the IsReadOnly property of the "final.doc" file to "true". It uses Path to specify the file, Name to specify the name of the property, and the Value parameter to specify the new value.

The file is a System.IO.FileInfo object and IsReadOnly is just one of its properties. To see all of the properties, type Get-Item C:\GroupFiles\final.doc | Get-Member -MemberType Property.

The $true automatic variable represents a value of "TRUE". For more information, see about_Automatic_Variables.

Set-ItemProperty -Path C:\GroupFiles\final.doc -Name IsReadOnly -Value $true

This example shows how to use Set-ItemProperty to create a new registry entry and to assign a value to the entry. It creates the "NoOfEmployees" entry in the "ContosoCompany" key in "HKLM\Software" key and sets its value to 823.

Because registry entries are considered to be properties of the registry keys, which are items, you use Set-ItemProperty to create registry entries, and to establish and change their values.

The first command creates the registry entry. It uses Path to specify the path of the HKLM: drive and the "Software\MyCompany" key. The command uses Name to specify the entry name and Value to specify a value.

The second command uses the Get-ItemProperty cmdlet to see the new registry entry. If you use the Get-Item or Get-ChildItem cmdlets, the entries do not appear because they are properties of a key, not items or child items.

The third command changes the value of the NoOfEmployees entry to 824.

You can also use the New-ItemProperty cmdlet to create the registry entry and its value and then use Set-ItemProperty to change the value.

For more information about the HKLM: drive, type Get-Help Get-PSDrive. For more information about how to use PowerShell to manage the registry, type Get-Help Registry.

Set-ItemProperty -Path "HKLM:\Software\ContosoCompany" -Name "NoOfEmployees" -Value 823
Get-ItemProperty -Path "HKLM:\Software\ContosoCompany"

PSPath        : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\software\contosocompany
PSParentPath  : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\software
PSChildName   : contosocompany
PSDrive       : HKLM
PSProvider    : Microsoft.PowerShell.Core\Registry
NoOfLocations : 2
NoOfEmployees : 823

Set-ItemProperty -Path "HKLM:\Software\ContosoCompany" -Name "NoOfEmployees" -Value 824
Get-ItemProperty -Path "HKLM:\Software\ContosoCompany"

PSPath        : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\software\contosocompany

These commands show how to use a pipeline operator (|) to send an item to Set-ItemProperty.

The first part of the command uses Get-ChildItem to get an object that represents the "Weekly.txt" file. The command uses a pipeline operator to send the file object to Set-ItemProperty. The Set-ItemProperty command uses the Name and Value parameters to specify the property and its new value.

This command is equivalent to using the InputObject parameter to specify the object that Get-ChildItem gets.

Get-ChildItem weekly.txt | Set-ItemProperty -Name IsReadOnly -Value $True

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.

You can pipe objects to this cmdlet.

This cmdlet generates a PSCustomObject object that represents the item that was changed and its new property value, if you specify the PassThru parameter. Otherwise, this cmdlet does not generate any output.

Set-ItemProperty is designed to work with the data exposed by any provider. To list the providers available in your session, type Get-PSProvider. For more information, see about_Providers.
