If you create/set an environment variable via the control panel
(system -> environment variables) the variable will be set in the
registry until removed (normally environment variables are stored
somewhere like HKEY_LOCAL_MACHINE\SYSTEM\ControlSet01\Session
Manager\xxxxxx - it varies by what version of windows you're running).
 If you set environment variable via a *.cmd or *.bat file, then those
settings exist for the length of the user's session and AFAIK no
temporary registry settings are made.
