Remove-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-ItemProperty
Description Remove a property and its value Usage Options -path string The path(s) to the item whose properties are being removed. 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(s) of the property to be retrieved. -include string Delete only the specified items from the Path e.g. "May*" this only works when the path includes a wildcard character. -exclude string Omit the specified items from the Path e.g. "*SS64*" this only works when the path includes a wildcard character. -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. -whatIf Describe what would happen if you executed the command without actually executing the command. -confirm Prompt for confirmation before executing the command. -credential PSCredential Use 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. CommonParameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutVariable. Example(s) Delete the 'Demo' registry value, and its data, from HKEY_LOCAL_MACHINE\Software\SS64 PS C:\>remove-itemproperty -path HKLM:\Software\SS64 -name Demo Again delete the 'Demo' registry value, but this time by changing location, and using a dot (.) to indicate the current location: PS C:\>set-location HKLM:\Software\SS64 PS HKLM:\Software\SS64>remove-itemproperty -path . -Name Demo
