I have no idea what you are talking about. I have used Vista since BETA 1. So has my family. Shutting the system down is anything but complicated.
I never said it is complicated. It's just by far less practical as in WinXP:
VISTA (I think that is the same, as we used to have it in the unholy Win ME too...)
Start -> shut down... -> Combobox (1 click to open drop down, search in the list, 1 click to select) -> OK ==> 5 clicks
Start -> Turn Off Computer... -> 3 Buttons (Stanby|Turn Off|Restart) ==> only 3 clicks & no Combobox!
