The Enhanced Mitigation Experience Toolkit is Microsofts best-kept security secret. Its easy to install EMET and quickly secure many popular applications, but theres a lot more you can do with EMET.

If an application does something your EMET rules disallow, EMET will shut down the application ? that's the default setting, anyway. EMET closes applications that behave in a potentially unsafe way so no exploits can occur. Windows doesn't do this for all applications by default because it would break compatibility with many of the old Windows applications in use today.

If an application breaks, the application will immediately shut down and you'll see a pop-up from the EMET icon in your system tray. It will also be written to the Windows event log ? these options can be customized from the Reporting box on the ribbon at the top of the EMET window.
