Any language version of Windows XP or Windows 2000 can be selected as a
platform for the test if the product is properly globalized. Of course, in the
case of localization testing, the localized version of the operating system can
be a wise choice, since that's the most likely environment for your application
in the real world. However, a globalized and localizable application, even after
it undergoes localization, must be able to run on any language version of the
operating system and with MUI installed.
You should run the application with MUI installed when your application
implements an MUI behavior, through pluggable UI, satellite dynamic-link
libraries (DLLs), or some other technique that adjusts the UI language to the
user's preferences. MUI allows the user to switch the UI language of the
operating system and thus you must make sure your application matches the
operating-system settings. You should verify the behavior of the application
when the user's default language of the UI differs from the other locale
settings. By doing so, you'll immediately see any problems in the way resources
are loaded and processed.
