Problem with the command set Path

[Halyn]

I would like to add a variable to the Path environment under XP at the following path through a bat file (to avoid going through the boring menu of Windows): C:\Program Files\Havas Medimedia\Common

I use the following command

set PATH =%PATH%;C:\Program Files\Havas Medimedia\Common

It works correctly, but when I close the console, the way I added does not appear in the path variable. Is there a way through the previous command to make the addition of the permanent way?

That modifications to the PATH command disappear when closing the console: this changes is valid for the current shell, as well as any child, but NEVER for the parent(s). For what you want to do that, I do not know if it is in the registry or a file.

I want to change the path through a batch, but these changes are not taken into account via console. Is there a way in the Windows registry which might allow me to pass this way?

Utility setx of W2K allows you to change variables of machines. You can also do the same thing via Windows Registry as follows:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment||Path
