While Microsoft is hard at work on the next major operating system, codename Windows 8, the leaks for the upcoming OS begin to roll in. Because Windows 8 is still in the pre-alpha stages, M3 to be exact, the feature sets and UI remain very limited or unchanged.
Today, Rafael Rivera and Paul Thurrott released series of images of upcoming features. Windows 8 will feature a built-in PDF reader, using Microsoft's Metro UI. Similar to Windows Phone 7 UI, the PDF reader will be clean, modern and "fast".
