UAC not a "security boundary."   
Does anyone know, why MS does not consider UAC to be a security boundary? 
And what are the trade-offs involved with making it one? Is it not possible 
to make it a security boundary?  It seems kinda anti-customer to say "if we 
find a security exploit in our code (in UAC) we won't fix it," doesn't it? 
I wish this would be fixed in Windows 7, but I admit I don't understand all 
the issues involved, so any help would be nice.

Hi,
Mark Russinovich explains it best in his presentation "Windows Security 
Boundaries". You can view it on technet spotlight here:
