Enhanced Protected Mode is a security feature that was introduced in Windows 8 and is now enabled by default in Internet Explorer on the Windows 8.1. Enhanced Protected Mode isolates untrusted web content in a restricted environment that's known as an AppContainer. EPM is an additional layer of protection. If you switch this feature off because you need to use an add-on, the overall security is still on the same level as was in the previous versions of Windows.
