[[System environment variables are defined by Windows 2000 Server and
are the same no matter who is logged on to the computer. Administrator
group members can add new variables or change the values, however.
User environment variables can be different for each user of a
particular computer. They include any environment variables you want to
define or variables defined by your applications, such as the path where
application files are located.]]
[[System Variables
You must be an administrator to modify a system environment variable.
System environment variables are defined by Windows and apply to all
computer users. Changes to the system environment are written to the
registry, and usually require a restart to become effective.
User Variables for User Name
Any user can add, modify, or remove a user environment variable. These
variables are established by Windows XP Setup, by some programs, and by
users. The changes are written to the registry, and are usually
effective immediately. However, after a change to user environment
variables is made, any open software programs should be restarted to
force them to read the new registry values. ]]

[[User environment variables for logged_on_user_name
The user environment variables are different for each user of a
particular computer. The variables include any that are set by the user,
as well as any variables defined by programs, such as the path to the
location of the program files.
System environment variables
Administrators can change or add environment variables that apply to the
system, and thus to all system users. During installation, Windows Setup
configures the default system variables, such as the path to the Windows
files.]]
