That is an interesting note. I've never seen "Power Users" contain
Authenticated Users on any system I've installed, but the page certainly
claims it. 
However, it makes no claim about Windows XP that I can see. Only about
Windows 2000, and it shows the difference for the server platform.

Yes, if this ia  default in a bunch of installations, we certainly
should. I've added a tracker to the installer to check for htis, and
we'll try toget it in there before release. I will also add it to the
installer/windows FAQ.
