Clear-ItemProperty - Powershell 1.0 CmdLet

Microsoft Windows PowerShell is a command-line shell and scripting tool based on the Microsoft .NET Framework. It is designed for system administrators, engineers and developers to control and automate the administration of Windows and applications.

More than hundred command-line tools (so called "cmdlets") can be used to perform system administration tasks and Windows Management Instrumentation (WMI). These cmdlets are easy to use, with standard naming conventions and common parameters, and standard tools for piping, sorting, filtering, and formatting data and objects.


Remove the property value from a property


-path string[]
        The paths to the items from which content is deleted.
        Wildcards are permitted.

    -literalPath string[]
        Like Path above, only the value is used exactly as typed.
        No characters are interpreted as wildcards. If the path includes any
        escape characters then enclose the path in single quotation marks.

    -name string
        The name of the property to be cleared, wildcards are not permitted.

    -include string[]
        Clear only the specified items from the Path. e.g. "ora*"
    -exclude string[]
        Omits the specified items from the Path e.g. "*SS64*"
    -filter string
        A filter in the provider's format or language. 
        The exact syntax of the filter (wildcard support etc) depends on the provider.
        Filters are more efficient than -include/-exclude, because the provider
        applies the filter when retrieving the objects, rather than having 
        PowerShell filter the objects after they are retrieved.
    -force SwitchParameter
        Override restrictions that prevent the command from succeeding, apart
        from security settings. e.g. Force will create file path directories 
        or override a files read-only attribute, but will not change file permissions.
    -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 using Get-Credential.
        This parameter appears, but it is not yet supported in any PowerShell core 
        cmdlets or providers
        Pass the object created by Clear-ItemProperty through the pipeline.
        (By default this switch is not set)

        Describe what would happen if you executed the command without actually
        executing the command.
        Prompt for confirmation before executing the command.
         -Verbose, -Debug,-ErrorAction,-ErrorVariable, -OutVariable.
