Fortunately, with Windows 7 it's no longer necessary to get write access to a process with higher priority. All you need to do is inject code into a process that can auto-elevate running at the
same integrity level, and there's nothing blocking you from doing that.
Which means that in effect the difference between medium and high integrity no longer exists, and the prompts have lost all semblence of purpose. You can argue that it's not a security issue, but fact remains that this change essentially makes UAC prompts
for Administrator accounts completely useless, so I ask again (and it'll get ignored again): why are they still there at all? What
is their purpose in Windows 7?
I'm wondering about the prompts too... as seen in an earlier reply... it's a little bit weird.
