<#
    .SYNOPSIS
        Creates the Win32_Software and Win32_Software64 WMI classes on the local computer or a remote computer.
 
    .DESCRIPTION
        The cmdlet creates two custom WMI classes for enumerating installed software from the standard registry provider. It creates a temporary mof file on the SystemDrive and calls mofcomp.exe to add the WMI class.
 
    .PARAMETER ComputerName
        The computer to create the custom WMI classes on. This defaults to localhost. If the target is a remote computer, Invoke-Command is used to execute the underlying function.
 
    .PARAMETER TempFilePath
        Where the temporary mof file is stored, this defaults to %SYSTEMDRIVE%\Win32Software_$([System.Guid]::NewGuid()).mof.
 
    .PARAMETER Credential
        The credential to use to connect to a remote computer. This parameter is ignored if the ComputerName is localhost, ".", or 127.0.0.1.
 
    .EXAMPLE
        Set-Win32Software
 
        Creates the two custom WMI classes on the local computer.
 
    .EXAMPLE
        Set-Win32Software -ComputerName server1.contoso.com -Credential (Get-Credential)
 
        Creates the two custom WMI classes on server1.contoso.com.
