Hello Linux Geeksters. In this article I will show you how to make your Ubuntu 13.04 Raring Ringtail look like Windows 8.

It is not difficult at all, you can do this in four small steps.
1. Download Windows 8 modern UI (metro) Metacity, extract the archive and move the theme to /usr/share/themes:
$ wget -c gnome-look.org/CONTENT/content-files/157024-Windows8.tar.gz
$ tar -zxvf 157024-Windows8.tar.gz
$ cp -R {Windows8,Windows8-Grey} /usr/share/themes
2. Do the same with FlatStudio theme:
$ wget -c gnome-look.org/CONTENT/content-files/154296-FlatStudio.tar.gz
$ tar -zxvf 154296-FlatStudio.tar.gz
$ cp -R {FlatStudio,FlatStudio?*} /usr/share/themes
3. Next, install gnome-tweak-tool:
$ sudo apt-get install gnome-tweak-tool
4. Use gnome tweak tool to select FlatStudio as your default Gtk+ theme and Windows 8 as your current theme.
This is it. Reboot and enjoy your Raring Windows.
