As promised, here’s three screenshots of Windows 7.

This first screenshot is just the Desktop. Windows 7 comes with a bunch of default wallpapers and you can set it so it changes every 30 minutes.

This one is just of the Start Menu. The little arrows next to certain programs open up menus, each one different depending on the item.
Getting Started opens up a menu with links to several places.
Stick Notes opens a menu so you can create new Notes for yourself (it’s a beefed up version of the Notepad in Vista’s Sidebar).
Paint and Notepad opens a menu of recently accessed items for each program.
And Internet Explorer opens a menu that contains your History.

In this screenshot, you can see how they have changed the Thumbnail Previews for the taskbar.
In the example, I used Internet Explorer. I opened Three tabs, and each tab gets displayed seperately in it’s own preview.
Not many programs support the new features, so don’t get your hopes up for Firefox to work like this, let’s hope they add it in 3.1.
The taskbar also groups open programs together if they are running on the same Process.
For example, look at my taskbar. If I were to open the Downloads Window of Firefox, instead of it being placed at the end of the list, it’ll be placed right next to the Firefox window, and given it’s own Preview window in the Firefox Thumbnail similar to Internet Explorer’s tabs.
The little icons at the bottom at similar to Quick Links in previous versions, but differ in many ways.
One of the ways they differ, is when you open an item that has been “pinned” to the taskbar, it’ll simply open there, instead of being opened at the end of the list.
You can see that example, with the location of Firefox’s taskbar item. When I close Firefox, the long bar will shorten and become a small icon.
Now, for the technical crap.
Windows 7 has the same requirements as Windows Vista, so there is no downgrade taking place anywhere (yay!).
However, Windows 7 does use less resources than Windows Vista overall. It has better RAM and Processor management than Windows Vista.
Windows 7 was built on the Windows Vista kernel, and fixes pretty much all of Windows Vista’s shortcomings.
I highly recommend that anyone planning on getting a new computer soon, that they hold off until Windows 7 is released to manufacturers. It’ll save you the headache of upgrading and it’s as stable as Windows 98 SE was back in the day.
