Beschreibung
The New-ItemProperty cmdlet creates a new property for a specified item and sets its value.
Typically, this cmdlet is used to create new registry values, because registry values are properties
of a registry key item.
This cmdlet does not add properties to an object.
- To add a property to an instance of an object, use the
Add-Membercmdlet. - To add a property to all objects of a particular type, modify the Types.ps1xml file.
Beispiele
Example 1: Add a registry entry
This command adds a new registry entry, NoOfEmployees, to the MyCompany key of the
HKLM:\Software hive.
The first command uses the Path parameter to specify the path of the MyCompany registry key.
It uses the Name parameter to specify a name for the entry and the Value parameter to
specify its value.
The second command uses the Get-ItemProperty cmdlet to see the new registry entry.
New-ItemProperty -Path "HKLM:\Software\MyCompany" -Name "NoOfEmployees" -Value 822
Get-ItemProperty "HKLM:\Software\MyCompany"
PSPath : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\software\mycompany
PSParentPath : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\software
PSChildName : mycompany
PSDrive : HKLM
PSProvider : Microsoft.PowerShell.Core\Registry
NoOfLocations : 2
NoOfEmployees : 822
Example 2: Add a registry entry to a key
This command adds a new registry entry to a registry key. To specify the key, it uses a pipeline
operator (|) to send an object that represents the key to New-ItemProperty.
The first part of the command uses the Get-Item cmdlet to get the MyCompany registry key. The
pipeline operator sends the results of the command to New-ItemProperty, which adds the new
registry entry (NoOfLocations), and its value (3), to the MyCompany key.
Get-Item -Path "HKLM:\Software\MyCompany" | New-ItemProperty -Name NoOfLocations -Value 3
This command works because the parameter-binding feature of Windows PowerShell associates the path
of the RegistryKey object that Get-Item returns with the LiteralPath parameter of
New-ItemProperty. For more information, see
about_Pipelines.
Example 3: Create a MultiString value in the registry using a Here-String
This example creates a MultiString value using a Here-String.
$newValue = New-ItemProperty -Path "HKLM:\SOFTWARE\ContosoCompany\" -Name 'HereString' -PropertyType MultiString -Value @"
This is text which contains newlines
It can also contain "quoted" strings
"@
$newValue.HereString
This is text which contains newlines
It can also contain "quoted" strings
Example 4: Create a MultiString value in the registry using an array
The example shows how to use an array of values to create the MultiString value.
$newValue = New-ItemProperty -Path "HKLM:\SOFTWARE\ContosoCompany\" -Name 'MultiString' -PropertyType MultiString -Value ('a','b','c')
$newValue.MultiString[0]

-Credential
Specifies a user account that has permission to perform this action. The default is the current user.
Type a user name, such as User01 or Domain01\User01, or enter a PSCredential object, such as
one generated by the Get-Credential cmdlet. If you type a user name, you are prompted for a
password.
Note
This parameter is not supported by any providers installed with PowerShell. To impersonate another user, or elevate your credentials when running this cmdlet, use Invoke-Command.

-Exclude
Specifies, as a string array, a property or property that this cmdlet excludes from the operation.
The value of this parameter qualifies the Path parameter.
Enter a path element or pattern, such as *.txt.
Wildcard characters are permitted.

-Filter
Specifies a filter in the format or language of the provider. The value of this parameter qualifies the Path parameter.
The syntax of the filter, including the use of wildcard characters, depends on the provider. Filters are more efficient than other parameters, because the provider applies them when the cmdlet gets the objects rather than having PowerShell filter the objects after they are retrieved.

-Include
Specifies, as a string array, an item or items that this cmdlet includes in the operation. The value
of this parameter qualifies the Path parameter. Enter a path element or pattern, such as
*.txt. Wildcard characters are permitted. The Include parameter is effective only when the
command includes the contents of an item, such as C:\Windows\*, where the wildcard character
specifies the contents of the C:\Windows directory.

-LiteralPath
Specifies a path to one or more locations. The value of LiteralPath is used exactly as it is
typed. No characters are interpreted as wildcards. If the path includes escape characters, enclose
it in single quotation marks ('). Single quotation marks tell PowerShell not to interpret any
characters as escape sequences.
