[<CommonParameters>] 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" -ConfirmExample 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 NoOfEmployeesParameters
-Confirm
Prompts you for confirmation before running the cmdlet.
| Type: | SwitchParameter |
| Aliases: | cf |
| Position: | Named |
| Default value: | False |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | 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.
| Type: | PSCredential |
| Position: | Named |
| Default value: | Current user |
| Required: | False |
| Accept pipeline input: | True |
| Accept wildcard characters: | 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.
| Type: | String[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | True |
-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.
| Type: | String |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | True |
-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.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | False |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | 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.
| Type: | String[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | True |
-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.
| Type: | String[] |
| Aliases: | PSPath |
| Position: | Named |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-Name
Specifies the names of the properties to remove. Wildcard characters are permitted.
| Type: | String[] |
| Aliases: | PSProperty |
| Position: | 1 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | True |
-Path
Specifies the path of the item whose properties are being removed. Wildcard characters are permitted.
| Type: | String[] |
| Position: | 0 |
| Default value: | None |
| Required: | True |

-UseTransaction
Includes the command in the active transaction. This parameter is valid only when a transaction is in progress. For more information, see about_Transactions.
| Type: | SwitchParameter |
| Aliases: | usetx |
| Position: | Named |
| Default value: | False |

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.
