How to change the Environment variable

[langhammer]

Is it possible to modify the Environment variable (not the path for
user!) via batch ?
Maybee changing the registryvalue in \HKEY_LOCAL_MACHINE ?

If I set path=%path%;c:\newfolder it is not enough and no environment
variable.
To change it about the explorer would be stupid, because its not
possible to change every entry on PCs by hand

You can use either of these tools:
setx.exe (Win2000 Resource Kit)
setenv.exe (ftp://barnyard.syr.edu/pub/vefatica/setenv.exe)

Note that your modification will be visible to all applications
launched ***after*** you have made the change. It will not
affect pre-existing applications.
