Solution 1

Try it :) :

{
  LCID lcId(0);
  NtQueryDefaultLocale(FALSE, &lcId);
  //... 
 
}

...or try to check the dependency of the "Default" entry under the registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\Locale

thanks, could you please tell me what I need to use "NtQueryDefaultLocale"? Because I get error message.

Probably, it will be possible to load and call it from the ntdll.dll (LoadLibrary/GetProcAddress/...) :)

It seems that I can load "ntdll" and seems also GetProcAddres works but
LCID lcId(0); NtQueryDefaultLocale(FALSE, &lcId); dosent work.

HINSTANCE hInstLibrary = LoadLibrary("ntdll.dll");
if (hInstLibrary)
{
FARPROC farproc = GetProcAddres(hInstLibrary, "NtQueryDefaultLocale");
LCID lcId(0);
NtQueryDefaultLocale(FALSE, &lcId);
FreeLibrary(hInstLibrary)
}

Nearly... :) :

typedef NTSYSAPI UINT_PTR (NTAPI *FP)(BOOL bUserProf, PLCID plcId);

LCID GetLocaleID()
{
LCID lcId(0);
HMODULE hLib = LoadLibrary(_T("ntdll.dll"));
if (hLib) {
FP fp = (FP) GetProcAddress(hLib, "NtQueryDefaultLocale");
if (fp) {
(*fp)(FALSE, &lcId);
}
FreeLibrary(hLib);
}
return lcId;
}
