1. You can now add anything to the Taskbar.
  2. Icons slightly expand when you hover over them on the taskbar.
  3. The "System" menu is more simplistic, and easier to navigate.
  4. You can change the login screen picture through the "Personalization" menu.
  5. The menu/lists that pop up when you right click on things now have the Aero Glass effect.
  6. The default icons for Folders have changed to be the transparent blue ones fe atured a long time ago.
  7. The Minimize/Maximize/Exit buttons on the top-right of a window have changed icons, and are a bit smaller than the Vista/7 counterparts.
  8. [BIG ONE]: There’s an "Upload" feature for Pictures, files, and videos. If you right-click a file, and click "Upload", you can make it automatically upload to a website of your choice. After uploading, a pop-up will appear saying it’s do ne, and clicking "OK" will cause the link/download link to the file to appear in the pop up box. I tried ImageShack and Facebook, and they work.
  9. Spanish, Chinese, Korean, and Japanese unicode(s) and settings are integrate d, so one can run foreign apps or use foreign keyboards without changing languages restarting.
  10. Explorer has been ported to .NET for increased performance and functionality.
  11. NTFS has been replaced by WinFS (this was the plan all along, but I couldn’t tell you about it before because of NDAs).
  12. New Aero Diamond theme, not just the maximize/minimize/close buttons.
