Add Hidden Regional Windows 7 Themes to your themes selection

During Windows 7 installation the aero themes that will be installed in your system will depend on the language or location that you have selected.  If my memory serves me right, during the early releases of Windows 7 all the regional themes were included and if you miss those themes you can still see them just by a few search and clicks!

To access the other regional themes type the following into the search box and hit the Enter key.

C:\Windows\Globalization\MCT

The MCT folder will show you the additional regional themes from Great Britain, South Africa, Australia,  and Canada.

You can go on to each every theme and copy or grab those wallpapers or go to the theme folder and double click the thumbnail to add the theme and make it available in the Personalization Settings.

In the screenshot below, as you can see the other regional themes are already added and installed.  For more cool themes you can also go to the Microsoft Personalization Gallery.
