Why not just run the initial program from a batch file.  That is...

rem This batch file will start the program and alter the ENVIRONMENT
@echo off
myprog.exe
call change.bat
rem This is the end of the batch file

Now... as myprog.exe runs it creates a text file to be run as a batch 
file called change.bat.  All it needs to do is something like this...

if it needs to change something, create a file that has...

@echo off
echo Setting variable to constant
set VARIABLE=CONSTANT
...
...

if it doesn't need to change something, just write one that says...

@echo off
echo Not changing a thing... :)
echo;

And thats it.  Since you are not changing the original batch file DOS 
won't complain about not finding the batch file and since it hasn't run 
the second batch file when the program terminates your changes will be made.
