Delete Windows Vista default power plans?

Hello,

Is it possible to delete the Windows Vista default power plans?

I'm getting very annoyed with not being able to select one from just
clicking on the system tray icon, it's silly why can't the choice of more be
available?

Is there some kind of Reg hack I can do to change this?

And no I can't just change the standard ones, I like to name them and there
all very different. Like not to turn the screen off, keep computer running
with lid closed etc.


Thanks very much!
