Configure the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> EMET >> "Default Protections for Recommended Software" to "Enabled". Note: The Enhanced Mitigation Experience Toolkit must be installed on the system and the administrative template files added to make this setting available. Due to a change in the registry structure for EMET 5.5, if the system has a previous version of EMET installed and configured, this setting needs to be set to "Not Configured" prior to the upgrade to EMET 5.5, and the new administrative template files copied to the appropriate area. The setting can then be re-enabled.
