// on systems prior to Windows Vista. It is not appropriate to use this
// function to determine whether a process is run as administartor.
//
// RETURN VALUE: Returns TRUE if the process is elevated. Returns FALSE if
// it is not.
//
// NOTE: TOKEN_INFORMATION_CLASS provides TokenElevationType to check the
// elevation type (TokenElevationTypeDefault / TokenElevationTypeLimited /
// TokenElevationTypeFull) of the process. It is different from
// TokenElevation in that, when UAC is turned off, elevation type always
