Windows 7 Toolbar
I have been using Windows 7 for about 2 weeks now and so far the experience has been fabulous. I am running build 7000, it is fast and stable.
One of the most noticeable and sleep new features is the new toolbar.
The toolbar automatically groups common windows together, which can then be expanded by hovering over the icon in the toolbar. In the snapshot above you can see that I have two instances of PowerPoint opened, as well as three instances of Internet Explorer 8. Also, and this is one of the sleekest features, you can see that I have placed both Tweetdeck, Zune, Word, Excel, and OneNote in the toolbar at a fixed location. So, whether the program is currently running or not, it will always be in the same location on my toolbar. In order to open the program you can simply click on the icon, or hold down SHIFT to open multiple new instances of the application.
Finally, if you look closely at the IE8 icon you can see that I currently downloading something, the progress being reflected by the green status bar in the icon.
