Windows Presentation Foundation Host (PresentationHost.exe)
Windows Presentation Foundation (WPF) Host (PresentationHost.exe) is the application that enables WPF applications to be hosted in compatible browsers (including Windows Internet Explorer 7 and Microsoft Internet Explorer 6). By default, Windows Presentation Foundation (WPF) Host is registered as the shell and MIME handler for browser-hosted WPF content, which includes:

For files of these types, Windows Presentation Foundation (WPF) Host:
Launches the registered HTML handler to host the Windows Presentation Foundation (WPF) content.
