Creating an Environment Variable
When you create or modify system environment variables, the changes
take effect when you restart the computer. When you create or modify
user environment variables, the changes take effect the next time the
user logs on to the system.
You can create an environment variable by completing the following steps:
-
Open the Environment Variables dialog box, as discussed previously. -
Tap or click New under User Variables or under System Variables,
whichever is appropriate. This opens the New User Variable dialog box or
the New System Variable dialog box, respectively. -
In the Variable Name text box, type the variable name. In the Variable Value text box, type the variable value. Tap or click OK.
Note
MORE INFO User profiles contain
global user settings and configuration information. They are created
the first time that a user logs on to a local computer or domain and are
different for local and domain accounts. A user’s profile maintains the
desktop environment so that it is the same each time the user logs on.
You can access Group Policy and use a preference item to create an
environment variable on computers throughout a domain by completing the
following steps:
-
Open a Group Policy Object for editing in the Group Policy Management
Editor. To configure preferences for computers, expand Computer
Configuration\Preferences\Windows Settings, and then select Environment.
To configure preferences for users, expand User
Configuration\Preferences\Windows Settings, and then select Environment. -
Press and hold or right-click the Environment node, point to New, and
then select Environment Variable. This opens the New Environment
Properties dialog box. -

create a user variable or System Variable to create a system variable. -
In the Name text box, type the variable name. In the Value text box, type the variable value. -
Use the options on the Common tab to control how the preference is
applied. In most cases, you’ll want to create the new variable only
once. If so, select Apply Once And Do Not Reapply. -
Tap or click OK. The next time policy is refreshed, the preference
item will be applied as appropriate for the Group Policy object in which
you defined the preference item.
