Windows 7® is a whole new version of Windows that is in a Beta testing.. But the features looks Great! Here are some of the features:
Improved taskbar and full-screen previews
The taskbar at the bottom of your screen is what you use to switch between the applications you've got open. In Windows 7 you can set the order in which the icons appear and they'll stay put. They're easier to see, too. Click once on the new large icons or bigger preview thumbnails and you're ready to go. You can even see a full screen preview before switching to the window.
Extended battery life
Performance improvements are about more than speed. For example, your laptop battery lasts longer with power-saving features, such as adaptive display brightness, which dims the display if you haven't used your PC for a while.
Windows Touch
While great for a lot of tasks, using a keyboard and mouse is not always the easiest way to do things. If you've got a touch-screen monitor, you can just touch your computer screen for a more direct and natural way to work. Use your fingers to scroll, resize windows, play media, and pan and zoom. Large touch-sensitive areas on the Start menu and the taskbar make it easy to use.
