If you wish to test with higher settings than Internet security config then the proactive config provide them by default without needing to confirm eventually neglected differences.
Did you confirm the differences by checking the configs entry by entry?
Indeed replicating the entire Proactive Config settings editing Internet Security config defaults will yield the same effect regardless of the name given to the customization though simply switching to Proactive config and taking the test again will require no effort and provide a way for everybody to take the test under the same conditions.
Likewise that was reason I asked you to switch to proactive config. I didn’t expect you to be so opposed to that whenever you are persuaded that you changed Internet security config defaults to the highest settings. :-\
It looks like steam and Internet explorer make use of the same component to display webpages but are different apps and thus are represented by the name of the corresponding containers steam.exe and iexplorer.exe
D+ ought to trigger an alert for any unknown app that attempt to invoke such components included in Internet Explorer/Windows Shell COM group.
