This tutorial will show you how to unlock regional themes in Windows 7 beta builds 6956 and higher.
1. Navigate to C:\Windows\Globalization\MCT.
2. Open a MCT-(AU, CA, GB, US, or ZA) folder for the regional theme that you want.
NOTE: AU, CA and ZA regions all have the same themes though.
3. Open the Theme folder in the selected region folder.
4. Select the .theme file to use it.
NOTE: Once you select a .theme file, Windows 7 will save it so that you will be able to change or select this theme again from within the normal Personalization window location.
5. Hide the Windows 7 System and Protected Operating System files.
6. Enjoy your new regional themes!
