In twinui.dll there are loads of bitmap images that are from the UI itself. It also calls itself 'Microsoft Windows Immersive Shell' and there are several references to 'tiles' and 'toasts', I don't know what toasts are though...

I wonder if this Immersive shell is actually unlockable in build 7850? I would think not, seeing as though there are not many registry entries relating to 'Immersive Shell' and the twinui.dll seems incomplete.

I was surprised to see this file in this build considering how early on in the development the build is. I guess this 'immersive' in Win8 is equivalent to the Superbar in Win7.

Both were known about but hidden. And both were present very very early on in the development process. My guess is that the builds with the newer logon screen can probably unlock 'Immersive Shell'. Its still very much incomplete in build 7850.

there is a new WebCam.exe which descript itself as 'Webcam Capture Application'
and Microsoft-Windows-WebcamExperience-WebcamExe, it has there images in its UI, obviously in Metro style,
apparently they are:
<AccessibleButton id="atom(idDelayedPhotoCaptureBtn)" ...
<AccessibleButton id="atom(idInstantPhotoCaptureBtn)" ...
<AccessibleButton id="atom(idVideoCaptureBtn)" ...

In twinui.dll there are loads of bitmap images that are from the UI itself. It also calls itself 'Microsoft Windows Immersive Shell' and there are several references to 'tiles' and 'toasts', I don't know what toasts are though...

in Android, a Toast is just a popup message window,
Windows Live Messenger's notify windows are Toast too,
and TwinUI's Toast looks like this, a content element and a close button :

<duixml>
	<HWNDElement resid="ToastContentHost" sheet="ToastContentStyle" layout="borderlayout()" contentalign="middlecenter" accessible="true" accname="resstr(6101, library(twinui.dll))" accrole="pane" active="mouse">
		<Element id="atom(ToastContentContainer)" layoutpos="client" layout="filllayout()" contentalign="middlecenter"></Element>
	</HWNDElement>
	<Element resid="ToastCloseButtonContainer" layoutpos="right" contentalign="topright" layout="filllayout()">
		<Button id="atom(ToastCloseButton)" contentalign="topright" layoutpos="top" accessible="true" accname="resstr(6103, library(twinui.dll))" accrole="pushbutton" active="mouse"/>
	</Element>
