That's not really useful, however, because the batch statement if "%windir%" == "" ... will test for an environment variable WINDIR in upper case. Your only real option is to write a program as suggested by the following question, and have it return a value which your batch file can test via "if errorlevel".

The benefit of this is it doesn't require anticipating the problem with ANSI.SYS escape sequences nor does it make you wait half an hour for the "Abort, Retry, Ignore?" prompt, as some versions of DOS do.
