How to write to the disk when the (Windows XP) user is restricted?

I need to write to an INI file as well as storing temporary files on the user's disk while running my program. How do I find the user's root directory where he/she is authorized to write if he/she is a so called restricted user?

function DefaultSaveLocation: string;
  P: PChar;
    returns the location of 'My Documents' if it exists, otherwise it returns
    the current directory.
  P := nil;
    P := AllocMem(MAX_PATH);
    if SHGetFolderPath(0, CSIDL_PERSONAL, 0, 0, P) = S_OK then
      Result := P
      Result := GetCurrentDir;
