Protected mode and enhanced protected mode reference

This section describes the API for Windows Internet Explorer Protected Mode and Enhanced Protected Mode (EPM).

Overviews/Tutorials

TopicContents
Introduction to the protected mode API

Protected Mode helps reduce the severity of threats to Windows Internet Explorer 7 and its extensions by eliminating the silent installation of malicious code through software vulnerabilities. Protected Mode accomplishes this goal using the integrity mechanisms of Windows Vista which restrict access to processes, files, and registry keys with higher integrity levels. The Protected Mode API enables software vendors to develop extensions and add-ons for Internet Explorer that can interact with the file system and registry from a low integrity process, such as Protected Mode Internet Explorer.

Protected mode broker functions

Windows Internet Explorer 8 in Windows Vista provides broker functions that allow access between applications, processes, and resources secured to other integrity levels.
