How to change PERMANENTLY environment variables from batch script?

[Cindy Parker]

Ok, I know. In a batch file I can change environment variables temporarily (=for the

current, remaining session) be entering e.g.



set CLASSPATH=D:\newpath;%CLASSPATH%



However these changes are not visible outside of the current session and furthermore they

are lost after a reboot.



Is there a(nother) way to change them PERMANENTLY from batch script?



I can imagine that there is a way by a regedit or VisualBasic script or 3rd party cmdline tool.



Again: I don't want to edit them manually e.g. in the "System" dialog in control panel.

The change should take place on cmdline from a script

Try setx.exe

You can try setting env variable using setx.exe(a windows 2000 resource kit utility)



http://ss64.com/nt/setx.html



Alternate is to set the values directly in env variable registry key(HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment). If you have plans to use this alternate, test it well before you deploy it in large scale.



Hope this helps...

Try setx.exe

Egghead Hooplehead alert. Changing the subject again to confuse people so

they wouldn't know to look at this thread for an answer to their original

question.

Thunderbird, at least, seems to be able to keep this thread together

despite the name change in the subject line. I agree, though, that

posters shouldn't change the subject line.



Besides the setx suggestion the OP could run the batch file at startup

every time, although that's not what he asked.
