No international themes are available
In the past, I have not been a big fan of the personalization features of Microsoft Windows. I found most of the Windows themes to be clunky, resource hogs, ugly, or all of the above. However, Windows 7 and the Aero interface is different, especially for those of us lucky enough to have a high definition resolution LCD monitor. Some of the included themes are quite elegant and engaging. In particular I like the image slideshow that serve as the background setting for many of the themes.
But there are several hidden international themes that do not appear as choices in the conventional United States-based installation of Windows 7. When you told Windows 7 that you were a resident of the U.S., the operating system hid the other international choices, but I don't like having my choices arbitrarily limited. There is a relatively simple way to add them to your list of available themes in the Personalization section of the Control Panel and it starts with a search.
