First, some demos on the UI from PDC using Windows 7 build 6933.winmain.081020-1842.
Very buggy demonstration on a Touch Screen application for Windows 7.
Different colors for different application when hovering your mouse in the taskbar. Is there even a point in doing this? Cool effect but lower specs PCs will cry.
Some modification on Quick Launch and the taskbar. Also a cool feature on Windows 7 called “Aero Peek”.
The boot screen for Windows 7. No logo or anything, just a text and a loading animation. I bet this won’t be final.
Video below is for the new Windows Live Messenger Wave 3. Seems like it is becoming smarter somehow with the user interaction.
