Description
The Clear-ItemProperty cmdlet clears the value of a property, but it does not delete the property.
You can use this cmdlet to delete the data from a registry value.

Example 1: Clear the value of registry key
This command clears the data in the "Options" registry value in the "MyApp" subkey of
HKEY_LOCAL_MACHINE\Software\MyCompany.
Clear-ItemProperty -Path "HKLM:\Software\MyCompany\MyApp" -Name "Options"
Parameters
-Confirm
Prompts you for confirmation before running the cmdlet.
Parameter properties

| 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, 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.
Parameter properties
| Type: | String[] |
| Default value: | None |
| Supports wildcards: | True |

(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 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.
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
Indicates that this cmdlet deletes properties from items that cannot otherwise be accessed by the user. Implementation varies from provider to provider. For more information, see about_Providers.

| 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. 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.
For more information, see about_Quoting_Rules.

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.
Inputs
String
You can pipe a path string to this cmdlet.
Outputs
None
By default, this cmdlet returns no output.
PSCustomObject
When you use the PassThru parameter, this cmdlet returns a PSCustomObject object representing the cleared item property.
Notes
Windows PowerShell includes the following aliases for Clear-ItemProperty:
clp
You can use Clear-ItemProperty to delete the data in registry values without deleting the value. If the data type of the value is Binary or DWORD, clearing the data sets the value to zero. Otherwise, the value is empty.
The Clear-ItemProperty cmdlet 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.
