IEZoneAnalyzer is a tiny tool that can help you make more sense of Internet Explorer's many security settings.
As an example, launch the program, choose Internet in the Security Zone box, and click View Effective Settings. You'll immediately see a single list of all your current settings, and how they've been set (user preferences, machine preferences or group policy). And in a click or two all this data can be exported directly to Excel, or saved as a CSV file.
IEZoneAnalyzer also makes it easy to compare security settings. You could save IE's configuration on your laptop, for instance, then compare it with your desktop settings, and IEZoneAnalyzer will immediately highlight any differences. Or, if you save your PC's IE settings now, then you could compare them with that baseline in a few months, and you'll immediately see if the settings have drifted over time.
And you can even compare your current configuration against Microsoft's recommended settings for particular security levels. If you're looking for maximum security, for instance, choose the "High" security template, compare it with your local settings, and IEZoneAnalyzer will again highlight any differences for you.
(The latest release has a few bug fixes, and now properly understands the default settings for IE10 on x64 Windows.)
