Description

The Remove-ItemProperty cmdlet deletes a property and its value from an item. You can use it to delete registry values and the data that they store.

Examples

Example 1: Delete a registry value

This command deletes the "SmpProperty" registry value, and its data, from the "SmpApplication" subkey of the "HKEY_LOCAL_MACHINE\Software" registry key.

Because the command is issued from a file system drive (PS C:\>), it includes the fully qualified path of the "SmpApplication" subkey, including the drive, HKLM:, and the "Software" key.

It uses the Name parameter to identify the registry value that is being deleted.

Remove-ItemProperty -Path "HKLM:\Software\SmpApplication" -Name "SmpProperty"

Example 2: Delete a registry value from the HKCU location

These commands delete the "Options" registry value, and its data, from the "MyApp" subkey of "HKEY_CURRENT_USER\Software\MyCompany".

The first command uses the Set-Location cmdlet to change the current location to the HKEY_CURRENT_USER drive (HKCU:) and the "Software\MyCompany\MyApp" subkey.

The second command uses Remove-ItemProperty to remove the "Options" registry value, and its data, from the "MyApp" subkey. Because Path is required, the command uses a dot ('.') to indicate the current location. It uses Name to specify which registry value to delete. It uses the Confirm parameter to request a user prompt before deleting the value.

PS C:\> Set-Location HKCU:\Software\MyCompany\MyApp
PS HKCU:\Software\MyCompany\MyApp> Remove-ItemProperty -Path . -Name "Options" -Confirm

Example 3: Remove a registry value by using the pipeline

This command deletes the "NoOfEmployees" registry value, and its data, from the "HKLM\Software\MyCompany" registry key.

The command uses the Get-Item cmdlet to get an item that represents the registry key. It uses a pipeline operator (|) to send the object to Remove-ItemProperty. Then, it uses the Name parameter of Remove-ItemProperty to specify the name of the registry value.

Get-Item -Path HKLM:\Software\MyCompany | Remove-ItemProperty -Name NoOfEmployees

Parameters

-Confirm

Prompts you for confirmation before running the cmdlet.

Parameter properties

Type:SwitchParameter
Default value:False
Supports wildcards:False
DontShow:False
Aliases:cf

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:False
Value from remaining arguments:False

-Credential

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.

Parameter properties

Type:PSCredential
Default value:Current user
Supports wildcards:False
DontShow:False

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:True
Value from remaining arguments:False

-Exclude

Specifies items that this cmdlet omits. The value of this parameter qualifies the Path parameter. Enter a path element or pattern, such as "*.txt". Wildcard characters are permitted.

Parameter properties

Type:

String[]

Default value:None
Supports wildcards:True
DontShow:False

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:False
Value from remaining arguments:False

-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.

Parameter properties

Type:String
Default value:None
Supports wildcards:True
DontShow:False

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:False
Value from remaining arguments:False

-Force

Forces the cmdlet to remove a property of an object that cannot otherwise be accessed by the user. Implementation varies from provider to provider. For more information, see about_Providers.

Parameter properties

Type:SwitchParameter
Default value:False
Supports wildcards:False
DontShow:False

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:False
Value from remaining arguments:False

-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.

Parameter properties

Type:

String[]

Default value:None
Supports wildcards:True
DontShow:False

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:False
Value from remaining arguments:False

-LiteralPath

Specifies the path to the current location of the property. Unlike the Path parameter, 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.

Notes

Windows PowerShell includes the following aliases for Remove-ItemProperty:

  • rp

In the PowerShell Registry provider, registry values are considered to be properties of a registry key or subkey. You can use the ItemProperty cmdlets to manage these values.

Remove-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.
