Fresh Windows 8 leaks on Monday reveal Microsoft’s Tablet tile UI and PDF reader functionality.
Rafael Rivera posted a number of screenshots on Monday that reveal Microsoft’s “Immersive” browser in Windows 8. Rivera speculates that the application is designed to run full screen only and that he is witnessing limitations trying to enable it on a pre-beta version of Windows 8. “One clue to the Immersive UI, however, exists in a new Immersive version of Internet Explorer, which looks and works much like Windows Phone’s IE Mobile, but uses the desktop IE 9 renderer,” writes Rivera.

WinRumors has previously written about Microsoft’s Immersive tablet experience. The UI will be driven by Microsoft’s Metro based design language. Microsoft will include a new application model codenamed “Jupiter” that will allow developers to create Silverlight based applications, deployed as AppX packages (.appx). The packages will be part of a new Windows application store, pre-installed with Windows 8. WinRumors understands the company will be looking to provide an easy way for existing Windows Phone developers to scale their applications for use with Jupiter.
The second secret that Rivera has uncovered is the existence of a “Modern Reader” application in Windows 8. The application includes its own PDF reader. Modern Reader is installed using Microsoft’s new AppX application package type. Rivera says “The application itself is simple enough. It displays PDFs in full fidelity, as you’d expect. You can zoom in and out, and there’s a page scrubber on the side of the application window for document navigation.”
