Ok I just want to know this, When WPI runs, will it have all of the side buttons? And wheere does it run, on the desktop or before you get to the desktop?

If you check the option to hide the additional buttons (Options, Config, Manual, About) when running from CD/DVD, only the upper buttons will be displayed when WPI detects, that it is not started from HDD.
Where WPI gets started depends on how you call WPI.hta. If you start it via GUIRunOnce, it is started before the desktop loads completely. I start my WPI and in the background I continue loading the Vista desk etc. In chapter 2 of the manual you can find some archives for starting WPI when windows installation is done.

Ok thanks.
