There are some hidden international themes that you can use on Windows 7.
1. Click on start and type in
Code:
C:\Windows\Globalization\MCT
if there is a problem with this try
Code:
D:\Windows\Globalization\MCT
and then press enter.
2. A window will pop up and show some folders.
MCT-AU for Australia
MCT-CA for Canada
MCT-GB for Great Britain
MCT-US for United States
MCT-ZA for South Africa
3. Open one of the folders and inside there are the folders that hold the theme files and also some lovely wallpapers.
4. Click on the folder that has the Country name and you will see a list of wallpapers..
5. Very nice indeed.
Have fun,
regards
