Downlevel, no. ISVs can declare the elevation behavior as long =

downlevel releases of Windows. This is for legacy programs only which = do

releases of Windows.

actually identified any of these. For these, allows, of course not. =
Defaults to prompt for, I believe yes.

OK thanks.
I infer that for some downlevel setup programs, Vista allows only =
"don't
run" and "run will full privilege" as was originally claimed.
