title: GetThreadLocale returns different value than GetUserDefaultLCID?
body: <p>To get the locale settings, e.g. short date format, we've always used GetLocaleFormatSettings with GetThreadLocale. This has always worked without problem until now.</p>
  
  <p>A couple of our users are getting different values for GetThreadLocale that don't match what they've configured in the regional settings in Windows 7. We've been unable to reproduce this no matter what we try, but I sent one user a test program to get the locale information, and sure enough GetThreadLocale returns a different LCID (1033) than GetUserDefaultLCID (2057). So instead of getting UK locale settings, they end up with US locale settings.</p>
  
  <p>Are we getting the locale information incorrectly? Should we be using GetUserDefaultLCID instead of GetThreadLocale?</p>
  
  <p>Thanks</p>
