Adding or Editing Environment Variables

Existing variables can be edited or deleted and new ones can be added in several ways. For temporary changes, the command " Set" can be used in scripts or in a command window. An example is:
set temp=C:\temp
Here, the %TEMP% directory has been changed from the default value. Note that the there must be no spaces on either side of the "equals" sign. Changes made with "Set" disappear when the command window is closed, thus rendering this method fairly uninteresting for the average PC user. A more useful application of "Set" is to list the environment variables. Open a command window and enter "set" to see what the variables are on your system.

A more permanent way to manage environment variables is provided in the System Properties dialog box. Open Control Panel-Performance and Maintenance-System (or right-click on My Computer and choose "Properties"). In the box that opens, click the "Advanced" tab to obtain the dialog box shown. Next, click the button "Environment Variables".

The figure shows the "Environment Variables" dialog box that opens next. It lists two kinds of variable- those that apply only to the current user and those that apply to the whole system. You can simply scroll down the lists to see what is on your system or you can edit the lists. Note that I have created a user variable %BACKUP% that gives the path to my one of my backup directories.
