DETAILED DESCRIPTION

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

 

PARAMETERS

 

-path <string[]>

Specifies the path to the item whose properties are being removed. Wildcards are permitted.

 

Required?	true
Position?	1
Default value	N/A - The path must be specified
Accept pipeline input?	true (ByValue, ByPropertyName)
Accept wildcard characters?	true

 

-name <string[]>

Specifies the names of the properties to be retrieved.

 

Required?	true
Position?	2
Default value	String.empty
Accept pipeline input?	true (ByPropertyName)
Accept wildcard characters?	false

 

-include <string[]>

Deletes only the specified items. The value of this parameter qualifies the Path parameter. Enter a path element or pattern, such as "*.txt". Wildcards are permitted.

 

Required?	false
Position?	named
Default value
Accept pipeline input?	false
Accept wildcard characters?	true

 

-force <SwitchParameter>

Overrides restrictions that prevent the command from succeeding, just so the changes do not compromise security. For example, Force will override the read-only attribute or create directories to complete a file path, but it will not attempt to change file permissions.

 

Required?	false
Position?	named
Default value	False
Accept pipeline input?	false
Accept wildcard characters?	false

 

-exclude <string[]>

Omits the specified items. The value of this parameter qualifies the Path parameter. Enter a path element or pattern, such as "*.txt". Wildcards are permitted.

 

Required?	false
Position?	named
Default value
Accept pipeline input?	false
Accept wildcard characters?	true

 

-credential <PSCredential>

Uses a credential to validate access to the file. <Credential> represents a user-name, such as "User01" or "Domain01\User01", or a PSCredential object, such as the one retrieved by using the Get-Credential cmdlet. If you type a user name, you will be prompted for a password. This parameter appears, but it is not supported in any Windows PowerShell core cmdlets or providers.

 

Required?	false
Position?	named
Default value
Accept pipeline input?	true (ByPropertyName)
Accept wildcard characters?	false

 

-filter <string>

Specifies a filter in the provider's format or language. The value of this parameter qualifies the Path parameter. The syntax of the filter, including the use of wildcards, depends on the provider. Filters are more efficient than other parameters, because the provider applies them when retrieving the objects, rather than having Windows PowerShell filter the objects after they are retrieved.

 

Required?	false
Position?	named
Default value
Accept pipeline input?	false
Accept wildcard characters?	true

 

-literalPath <string[]>

Specifies a path to the item property. 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 Windows PowerShell not to interpret any characters as escape sequences.

 

Required?	true
Position?	1
Default value
Accept pipeline input?	true (ByPropertyName)
Accept wildcard characters?	false

 

-whatIf

Describes what would happen if you executed the command without actually executing the command.

 

Required?	false
Position?	named
Default value
Accept pipeline input?	false
Accept wildcard characters?	false

 

-confirm

Prompts you for confirmation before executing the command.

 

Required?	false
Position?	named
Default value
Accept pipeline input?	false
Accept wildcard characters?	false

 

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, and -OutVariable. For more information, type, "get-help about_commonparameters".

 

RETURN TYPE

None

 

NOTES

 

For more information, type "Get-Help Remove-ItemProperty -detailed". For technical information, type "Get-Help Remove-ItemProperty -full".

 

In the Windows 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.

 

When specifying multiple values for a parameter, use commas to separate the values. For example, "<parameter-name> <value1>, <value2>".

 

You can also refer to Remove-ItemProperty by its built-in alias, "rp". For more information, see About_Alias.

 

EXAMPLE 1

 

 

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

 

Because the command is issued from a file system drive (C:\PS>), it includes the fully qualified path to 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.

 

EXAMPLE 2

 

 

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