[<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.
Remove-ItemProperty -Path "HKLM:\Software\SmpApplication" -Name "SmpProperty"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.
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".
PS C:\> Set-Location HKCU:\Software\MyCompany\MyApp
PS HKCU:\Software\MyCompany\MyApp> Remove-ItemProperty -Path . -Name "Options" -ConfirmThe 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. The Confirm parameter requests a user prompt before deleting the value.
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.
Get-Item -Path HKLM:\Software\MyCompany | Remove-ItemProperty -Name NoOfEmployeesThe 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.
Parameters
-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, as a string array, an item or items that this cmdlet excludes 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 Exclude 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.
| Type: | String[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | True |
-Filter
Specifies a filter to qualify the Path parameter. The FileSystem provider is the only installed PowerShell provider that supports the use of filters. You can find the syntax for the FileSystem filter language in about_Wildcards. 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. 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.
| Type: | String[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | True |
-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.
For more information, see about_Quoting_Rules.
| Type: | String[] |
| Aliases: | PSPath, LP |
| 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 |

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-ItemPropertyis designed to work with the data exposed by any provider. To list the providers available in your session, typeGet-PSProvider. For more information, see about_Providers.
