Anything you can execute from the windows command line can be done through Send Event.
Start with "cmd /c " and if you have multiple commands string them together with "&" or "&&". The Windows help on command line will give you a lot of good info.
Another way of doing it if you need more power is to construct your VBscript or PowerShell syntax in a global field, use Export Field Contents to export it to the hard disk and then use Send Event to execute it.
Plugins can be used too.
