*. It uses the Nautilus elementary as the file manager.
*. Comes with Windows icons and wallpapers.
*. Aero style buttons.
*. Windows fonts (I think this is illegal actually, so use it at your own risk).
*. Uses the Emerald theme for Gnome, and be aware that, when you install Longhorn pack, it'll automatically remove the installed Emerald GTK+ themes!.
How can I install it ?
1. First you have to download it (about 33.2MB in size).
2. Then extract the content to somewhere in your HDD.
3. Then double click the file called "install.sh" inside the extracted folder.
4. When asked, choose, "run in Terminal" and follow the instructions on the screen and everything will be installed automatically. :). That's it!.
