Before we go through the Windows 8 Build 7989 fully, Windows 8 Build 8030 screen shots were leaked to the internet. Legitimate source leaked the screen shots to  WinBeta.org. Key features noticed in the screenshot is the new user interface that was shown in the Computex and D9 conferences. There is a small difference though. There is a added notification system at the bottom right hand corner.

“Here is what we know so far. The latest internal build as of this post is 8030.0.110620-1742. This is a Milestone 3 build and was compiled on June 20th. Multiple branches of Windows 8 are being built off the winmain trunk. Microsoft is still facing a ton of bugs with their Windows 8 code as the company faces some big architectural changes to support the promised features. In fact, in these builds, we are seeing incomplete and untested code. Applications and features that worked in the past are now facing problems with user interface bugs.” mentioned in the Winbeta.org.
