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 CLASSPATHnewpath;%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...

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.
